Don't assume that pressures are always positive

When planning a dive, the dive could use more gas than is in the cylinder.
So getting a negative end pressure is a useful indication to the user that
there plan might not be a good one.

Planner: track gas consumption in cylinders and samples

This commit is a little bigger than I usually prefer, but it's all
somewhat interconnected.

- we pass around the cylinders throughout the planning process and as we
  create the plan we calculate the gas consumption in every segment and
  track this both in the end pressure of the cylinder and over time in
  the samples
- because of that we no longer try to calculate the gas consumption after
  being done planning; we just use what we calculated along the way
- we also no longer add gases during the planning process - all gases
  have to come from the list of cylinders passed in (which makes sense
  as we should only use those gases that the user added in the UI or
  inherited from a the selected dive (when starting to plan with a dive
  already selected)

With this patch I think we are close do being able to move all of the
planning logic back into the planner.c code where it belongs. The one
issue that still bothers me is that we are juggling so many dive
structures and then keep copying content around. It seems like we should
be able to reduce that.

Planner: clean up the function that tracks our gases

This doesn't add gases. It just makes sure they are there.

Planner: only update the plan after the cylinder data has been updated

This way we avoid trying to create a dive from the plan while the plan
references the cylinder that has just been changed.

Hide DiveHandlers and GasTexts when on profile mode too.

When switching from PLAN or ADD mode to PROFILE, we
kept the dive handlers visible, not anymore.

Hide the DiveHandlers that are not entered by mouse.

We need to create them, even if we don't display ( only because it
was a pain to correctly track them from the model ) - so, hide them
if it's not entered by mouse, but a deco one.

Do not show 'trash' icon for deco stops.

Besides not deleting them, we shouldn't offer the icon for it.

Do not offer an editor when double-clicking REMOVE on the planner.

The  planner would offer an text-editor if the user double
clicked it's remove column. forbidding that.

HTML: Quote the '<' and '>' operators before inserting break tags

The smaller than and greater than operators should be quoted before
inserting the <br> tags in HTML. Otherwise breaks will be quoted which
corrupts the format.
