#5 synchronize outline selection from source

[Anonymous]

At the moment there's only synchronize from outline 2
source (when the user clicks in the tree, in the sorce
the corresponding item is selected/jumped).

A very simple to implemnet and useful feature would be
"synchronize outline selection from source" :
- in the titlebar of the outline, sould be a toggle
button with with this operation.
- when the button is toggled, moving the caret in the
source, would change the outline selection too.
