* fixed a bug in hierarchal shematics where a loop (e.g. same file included at different points in the 
hierarchy)  would cause infinite memory use.   
* added a edit footprint hotkey to eeschema, since it seems I'm always editing '0603' '0402' etc. on the 
common components, and it was difficult to edit this information before.

solved drc.cpp error (pcbnew crashes in track creation or edition). very minor other changes (translation)

--no commit message

listboxes.cpp problem: apply to window version only. Some other very minor enhancements and bug fixes

Use wxWindowDC instead of wxClientDC as function parameters since we cannot assume that wxPaintDC inherits from wxClientDC

Use full path to executables under Mac OS X, this is because the Mac OS X app launcher doesn't support classic cmd-line parameters

cvpcb:	set flag wxFRAME_FLOAT_ON_PARENT when create the footprint 3D frame and the display frame
