Improve profile display in planner

Browse source 
This patch allows the planner to save the last manually-entered
dive planner point of a dive plan. When the plan has been saved
and re-opened for edit, the time of the last-entered dive planner
point is used to ensure that dive planning continues from the same
point in the profile as was when the original dive plan was saved.
Mechanism:

1) In dive.h, create a new dc attribute dc->last_manual_time
   with data type of duration_t.
2) In diveplanner.c, ensure that the last manually-entered
   dive planner point is saved in dc->last_manual_time.
3) In save-xml.c, create a new XML attribute for the <divecomputer>
   element, named last-manual-time. For dive plans, the element would
   now look like:
   <divecomputer model='planned dive' last-manual-time='31:17 min'>
4) In parse-xml.c, insert code that recognises the last-manual-time
   XML attribute, reads the time value and assigns this time to
   dc->last_manual_time.
5) In diveplannermodel.cpp, method DiveplannerPointModel::loadfromdive,
   insert code that sets the appropriate boolean value to dp->entered
   by comparing newtime (i.e. time of dp) with dc->last_manual_time.
6) Diveplannermodel.cpp also accepts profile data from normal dives in
   the dive log, whether hand-entered or loaded from dive computer. It
   looks like the reduction of dive points for dives with >100 points
   continues to work ok.
The result is that when a dive plan is saved with manually entered
points up to e.g. 10 minutes into the dive, it can be re-opened for edit
in the dive planner and the planner re-creates the plan with manually
entered points up to 10 minutes. The rest of the points are "soft"
points, shaped by the deco calculations of the planner.

Improvements: Improve code for profile display in dive planner

This responds to #1052.
Change load-git.c and save-git.c so that the last-manual-time is
also saved in the git-format dive log.

Several stylistic changes in text for consistent C source code.

Improvement of dive planner profile display:

Do some simplification of my alterations to diveplannermodel.cpp

Two small style changes in planner.c and diveplannermodel.cpp
