Code review comment for lp://qastaging/~3v1n0/unity/panel-p-cleanup

** Note, I couldn't test any bug that dealt with multi monitors. **

Ok, lots of code. Confirmed this branch fixes all of these bugs:

Bug #655184: Top bar - Menus should be condensed to fit panel/overlay of appmenu
Bug #839690: Topbar - window controls for maximised windows in the top bar should conform to Fitts's law
Bug #875932: window selected via ALT+F1 doesn't get focus in unity
Bug #934680: Window management - Dragging down a maximized window from the panel has not predictable results
Bug #936425: Not minimizable windows have an enabled "minimize" button on the unity panel
Bug #939054: HUD maximize button affects Dash
Bug #962410: Menu bar not transparent when invoking dash with super key whilst HUD enabled and vice versa
Bug #963118: Windows controls lost if dash is opened after HUD
Bug #963134: Opening HUD after dash shows window title in the panel
Bug #970420: Super+Tab, super, loses focus
Bug #971947: PanelMenuView causes gtk assertion to fail
Bug #940683: Panel opacity toggle doesn't quite work

When the test are done this branch will be look good :). Awesome work!
