Title: Improved UI for Scala completions. 

- when a proposal is chosen, its parameter names are inserted
in place of the arguments, and the editor is put in 'link' mode:
Tab moves the caret to the next argument, Esc and ';' move the caret
to the end of the argument list (and exits the linked mode). Hitting
moves the caret to the end, unless it comes after an opening
brace -> that means a closure is needed, and the editor is put out
of the linked mode

- context information works now. A method signature (parameter names and
types) are shown above the completion point, and the current argument
is correctly highlighted (bold). When the cursor leaves the argument list,
the context information window is now removed.
