- removing duplicate chunks of code -> hide unused sockets now works
- moving some functions to the files that they get called from -> view all/home
- made duplicate a macro operator like the other places that work like this, eliminating the unnecessary transform-related property there still
- removed a few chunks of unused code
* Restored Mute and Hide Operators, M and H keys respectively
* Restored Make Links Operator (F). However, I can't figure out how to set the sockets so that this can be used
* Made Alt-RMB the new hotkey for breaking links by dragging, since Alt-LMB was taken for panning already
* Fixed a nasty bug which meant that it was impossible to set an active node. Was caused by ntreeCopyTree() getting called when compo updates were done and clearing the active flags. The active flag clearing is only really needed for the "internal_select" case which is only used for duplicating selected nodes (from Shift-D duplicate).
* Recoded click-selection code. Was a mess of old code, bad exceptions from the old code half ported, duplicate operators, unnecessary flags/modes.
* Fixed bug #19927: compositing node groups can't be access via "tab" or ungrouped via "alt+g". Was probably related to the active group not being able to be set.
* Made resizing nodes work again. Again, this was due to the active node bug.
* Made adding a new group with Ctrl-G correctly update the views
Contributors list isnt used much in our C code so probably its easier if people just use svn blame for this.
Can change if this isnt acceptable but I guessed people didnt care so much since most scripts had no header.
