Patch for Templates plugin - fix keyboard handling in dockable panel.
With this patch, the Enter key now applies the selected template if it's a leaf node, or expands the current node if it's a folder, instead of inserting a newline in the text area.
Patch against templates/TemplateDockable.java
Since the ENTER key is the only key being handled by the dockable, I removed the KeyListener-based implementation and used a key binding instead. This results in the same functionality as provided by Nick's patch.
Changed in revision 14121.
