Fixes/tweaks for NanoUI, updates to new PDA 

These changes were made by TG coders, I've added them to BS12:
* Transfer open ui instances when transferring a user to another mob
* Runtime fixes in the NanoUI Topic and nanoclose client verb
* Return focus to the map when a NanoUI is opened

New additions:
* Updated NanoUI's nanomanager with update_user_uis and close_user_uis procs. These procs allow you to update and close uis for a specific user and optionally a specific src_object and/or ui_key.
* Added a link to the new NanoUI wiki page in the TemplatesGuide.txt file.
* When a user sends or recieves a Message using a PDA, the UI (if open) will now update instantly to show the sent/received message (this uses the new nanomanager.update_user_uis proc).
