Add support for OpenGL software rendering.

Browse source 
In some systems, the default Qt hardware renderer is buggy. There's a Qt
option for forcing software rendering. This commit adds support for a
new environment variable, ANKI_SOFTWAREOPENGL, that, when set, will
prompt Anki to force software OpenGL in Qt.
