Custom animation. Changed the list of standard animation transitions.
Default animation delay 0.0.
Update thumbnails label when idle: no hurry.
Always change panelWindows gravity throw animation (set time to 0 if animation is not needed).
Call animation in show/hide/setOpacity etc. in any case because of callbacks: let animateToState decide whether the actual animation is needed as well as cancel old and/or set new callbacks.
restoreNaturalSize: animate height only if it is animated in show/hide; added time, callback, scope and transition.
Minor fix: getText() should always return StLabel.get_text() even if it is "".
Simplified thumbnails label.
Preferences: allow multiple bindings for sensitivity.
Bind thunbnails panel background properties to both windows-theming and !windows-background-panel.
Color and opacity in one row.
Close thumbnails panel when the app icon is clicked.
addScaleColorButton instead of addColorButtonOpacity.
Missing period.
Thumbnail panel custom text color and size.
Fix debug levels.
addRow first argument is any widget, not just a label.
Deleted unnecessary actor removes in some destroy's. Added this._clicked.destroy in dbFinWindowThumbnail.destroy.
Debugging to special panel instead of file.
