unload style sheet
remove blank spaces
New action "autoScroll", trigger default autoscroll manually

Few users want to have autoscroll, however if autoscroll is enabled
it cannot be bypassed on secondary action since it is registered
before emc. It is better to just trigger it manually as an action.
new action "Remove current tab"
don't pass byMouse to removeTab animation

This will ignore mouse position, byMouse is used mostly when
actually closing tabs with mouse over tabbar for animating tab
positions relative to the mouse.
Added "undoCloseTab" action
Removed some commented code for bookmarks menus
Version 0.4.4
