New module interface [GuiTools]
First iteration and test (but not working)
It works on certain values ?
Fixes GuiTools (but only Left align works)
Alignment is fixed !
Point values are now floats
Notes
Added a Theme module
Added open for doc to compile (again)
Cleanup
Use of rect_print in item#draw
Use of rect_print for key_button as well
Poor attempt at vertical centering
CLeaned tests on main menu
Main menu using GuiTools as well
Merge pull request #59 from GL-MPRI-2014/gui_tools
