Pinline and Close Button mods

[madprops]

The pinline can now be dragged to define the delimeter between pinned tabs and normal tabs.

For instance if you move the pinline downwards, the items it crossed below will become pinned.

If moved upwards, the items it crossed will become normal.

The pinline now has its own settings category, I added some settings.

Also some modifications on the close button.

Also in theme there's some Border settings at the bottom to apply a colored border to the whole sidebar/popup.

Icons and close buttons now have 2 hover effects.

There's the normal/item hover, which makes things appear when an item is hovered with the mouse.

But now there's a global hover when the mouse enters any part of the sidebar.

Close buttons now have global hover by default.

They hide again 1 second after the mouse leaves.
