Code review comment for lp:~brandontschaefer/unity/lp.1101310-fix-launcher-resize-window-buttons

To help with review, since most of the diff +/- is due to just moving the WindowButton* to unity-shared:

New class OverlayWindowButtons:
1156 === added file 'unity-shared/OverlayWindowButtons.cpp'
1237 === added file 'unity-shared/OverlayWindowButtons.h'

Test:
1094 === modified file 'tests/autopilot/unity/tests/test_panel.py'

DashView changes:
11 === modified file 'dash/DashView.cpp'

HudView changes:
159 === modified file 'hud/HudView.cpp'

Those are most of the real changes.
