'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.

use QWebView to show the user manual

Looks like the QTextBrowser can't render the manual correctly.
Also, QWebView provides a better way to find contents on a webpage,
which is an important feature for an user manual (to be implemented).

fixing planner's gas dialog

Before this commit this dialog had a weird behavior in which
when it was shown, the whole screen was still active. In case of a
alt+tab, this dialog is sent to behind the application window, but still
visible in the task bar.

This commit basically changes this behavior to a regular pop-up.

Added a new widget to control the Planner

Added a new widget to control the DivePlanner, now we
have two widgets, a graphics one and a qt sidget based one.
the Technical divers will most likely use the QtWidget one
while the hobbists will most likely use the QGraphicsView
one. there's not a option to choose one, they both will
appear at the same time.

Next step: make the screens to work.

Started the Model to handle the DivePoints

Started the model to handle the divepoints between the
Qt Widget interface and the QGraphicsView one. good thing
is that we share code. Bad is that a model is harder to
work, but doable. :)

With this finished ( in a couple of commits ) one can
insert a point on the Qt widget or on the graphics view
and it will be 'mirrored' to both interfaces.

First implementation of the Shared Model for the Planner

This implementation of the shared model already shares
some, but not all data between the two views, but it's
already a huge improvement. When the user clicks on the
visual planner, it will update the view on the qt-widget
based view. The editing of the view is still not allowed,
and removing nodes is not allowed too ( yet. )

Moving Handler on Graphics Updates the Model on the Planner

Unfortunately, the graphics will move back to it's original
