'Cancel' action Cancels editing Cylinders.

Made the default 'Cancel' action correctly cancel
the cylinder edition. This is needed only because
we bypassed the default behavior on Qt that took
care of this, because we wanted to have more control
on how the view would update the items accordingly
with wich one of the cylinders were selected
on the edition pane - the pressure and size of the
cylinders needed to have it's data set, but the Qt
Model/View system *thinks* that cancel-edition is
simply 'do not commit the edition data, then.' wich
would not work with us, because we passed the strange
data already. So, I created a backup data that serves
us very well. When the user cancels, this backup data
is added back on the cylinder, making everything as
it was before.

Added the code to revert Weigths when user cancels edition

This is a follow up commit to the previous one that
enabled cancel for cylinders, everything in the commit
log for the cylinders also applyes here.

Fixes incorrect editing policies.

The Working Press didn't correctly updated when there was a 'bar'
or 'psi' in the string ( and that was defalt behaviour );

The o2 didn't correctly updated when there was a '%' on the string
(and that was default behaviour ),

The He didn't correctly updated when there was a '%' on the string,
and that was also default behavior.

Now all of them correctly updates.

Fix for double-rendering, double selection and other annoyances.

This patch fixes a thing that I run into when trying to implement
the multi-edition system. Whenever a dive was selected, via mouse
or keyboard, it had two stages: first, it would select the previous
and the current ( and thus, render the profile of the current) and
then whould release the previous and select the current again ( and
thus, rerendering the profile again, plus a few other things. )
With the multi-edition system this caused a more severe bug, since
the edition of the dives is directly applied as soon as the text fields
changes, as soon as we selected any dive on the list, the 'before' dive
would be modified by the 'current'. This patch fixes this - but since it's
just a 'code removal' patch, this can led to bad things in the future,
I tested it quite a bit, but didn't found anything, no regression.
*fingers crossed.*

Enable Multi Dive Editing.

This patch enables multi dive editing on the selected
dives. It's a bit of big patch where I reworked how it
worked since it was written just for a single dive.
this means that this can introduce bugs - I'v tested it
quite a bit but a thing could slip thru my fingers. :)

How this is supposed to work:

Select a few dives that you want ( one or more ) then
click on the field that you wanna edit / multi edit, and
press 'accept'. *only* the edited field will be modified
thru all dives.

Next patch - I'll change the bg color of the edited fields.A

Change bg of edited parts of the dive on the interface

Change the background color of edited parts of the dive
on the interface. Specially util if you are editing multi
dives in a single step, and went to eat something or did
anything else for five minutes, then come back and don't
quite remember what did you changed. now it's in a cute
yellowish background.

Good deal of code cleanup.

This is a bit of code cleanup that I'm not sure that will
pass, since it's all macro-based, but I don't have a thing
against macros at all. Sometimes they helps us keep a better
and cleaner code base. I think I managed to remove around 120
lines of code, wich isn't much, but I replaced it by 14. and the
code is now easyer to maintain, so hooray.

Position the X and Y labels of the Rulers

Position the X and Y labels of the rulers, this way
it's a bit more clear the deepness and the length
of the trip. It's still not the best approach, but
I'm getting close.

Plug the Cancel action on the Dive Planner Table and start the 'ok' code.

Plug the cancel action on the dive planner ( before that, only by
hitting the 'ESC' button things worked, so now you can also click
on the Cancel box that's on the right of the planner profile window.

Also, the beginning of the 'ok' code is also at place.

Move the creation of the dive plan to the model

The dive plan was bein created on the Profile, this
While this worked out, it created a bit of spaggethi
code, so now the model will take control of *everything*
on the planner.

I tested it quite a bit and doesn't seems to have appeared
a regression, wich is good.

Now that a dive plan is bein created, I can just save it. :)

Ok on the planner now correctly creates a Dive.

Ok on the planner now correctly creates a dive,
a few remarks, tougth:

1 - the number of the added dive is always 0
( but I may be testing it wrong )

2 - the information pane is working only when
the mouse is clicked, this is a regression and
it will be fixed. ;)

Use the same line dimensions as the profile, on the planner.

The Planner should be 'almost' like the profile, with the possibility
to use the mouse and keyboard to input a new plan, so this is a bit
of 'getting there.' I don't like too much code duplication but since
the current Profile Graphics is a crude cut-and-paste from the old
Cairo backend, it's easyer to start from scratch and have it well
organized as Qt code.

Plotted the Scale on the Ruler ( depth / time ) on the planner

Plotted the Scale on the Ruler in the planner.
There's a tiny bit issue - mostly noticiable while resizing,
but it's not a killer.
