Add some fancy cairo-drawing if the compositor is in use
FIXME: add theming possibilities for roundness, colors, border-width and alpha
Tweak padding of tabwin
Change visual of minimized apps in tabwin
Remove [] from label and increase saturation a little
Fix ellipsizing on app-buttons in tabwin
Improve drawing for non-composited tabwin
Use GTK_STATE_SELECTED color to draw the border, like in xfsm-logout
Pick up gtk-colors in composited version too
Make border-width property functional again
Install a few more style properties
FIXME: alpha, border-alpha
Fix property types
thanks Nick
Rename radius to border-radius and set relative default border
Some default values and variable names are now the same as in notifyd
Fix up default icon and bump png-icon-size to 64px
Ensured it scales down to 48px very nicely, so it's better than scaling 48px up
Small tabwin code improvements
Experiment with button events.
