Fix QString Usage

Fixes QString Usage. to return a Empty QString, one should
return a QString() and not a QString(""), and to check if
the string is empty, one should check for string.isEmpty()
instead of "string != "" ", because the latter will create
a new QString, then call the != operator, less function calls,
better code.

Use the same code for command line and gui for file handling.

The Command line execution of Subsurface happened before the
GUI was created, this leaded to various bugs by me(tm) over
time. This patch seems to fix all of those, by reusing the
same code for GUI interaction and CommandLine interaction.

I had to rework how the main.c worked, it used to be C code
calling C++ code, and this is non desirable, since C doesn't
really understand C++.

I Moved all of C-related code to 'subsurfacestartup.c/h' and
created a tiny wrapper to call it, so all of the C code is still
C code, and the new main.cpp calls the mainwindow->loadFiles and
mainWindow->importFiles to get rid of the bugs that happened before.

Enable the CC SetPoint on the planner, also input bug fix.

Enabled the CC SetPoint settings on the table, changing
it will automatically reflect the canvas. Also fixed a bug
that prevented the 'Air' handling on the diveplanner
table to show the list of options using arrow up and down.

Plug most of the dive planner - non - model stuff.

Plug most of the dive planner controls that weren't
plugged yet - StartTime, ATMPressure, BottomSAC,
DecoStopSAC, LowGF and highGF are being used by
the calculations now.

Signal that the model changed when editing plan specific information.

Signal that the model changed when editing plan specific information,
when you changes the ATM pressure or any other information, the
graphic of the plan will be generated again to mirror your actual dive.
