[PATCH] Minor fix for linkmap actions

[Piotr Piastucki <leech miranda gmail com>]

Hi,

There seems to be a small issue in the editable state handling in new 
linkmap module (see http://piastucki.bdl.pl/meld/linkmap_actions.png, 
only the middle pane is editable) .
The attached patch fixes the issue.

Cheers,
Piotr
