Added Reload Lua plugins.

This is initial support for reloading Lua plugins without
restarting the application.

Still todo:
- Deregister FileHandlers
- Support deregister ProtoField with existing abbrev (same_name_hfinfo)
- Add a progress dialog when reloading many plugins
- Search for memory leakages in wslua functions
