change white background for icons in PouInstanceVariablePanel to transparent
in wxPython 2.8 panel has white background and therefore white
background is appropriate, but in wxPython 3.0 panel has grey
background (on GNU/Linux and on Windows).
Transparent background looks good on both wxPython versions and on all platforms.

change white background for project tree element to transparent
because on GNU/Linux project tree has grey background, therefore
white background looks not good.
