Fix bug 201257 -- clean up use of nsIControllerCommandManager by editor:

Renaming nsIControllerCommandManager to nsIControllerCommandTable to reduce confusion.
Moving the immutability flag from the nsBaseCommandController to the nsControllerCommandTable.
Renaming the 'refcon' on nsIControllerContext to 'context', and giving nsIControllerContext an Init() method that optionally takes a command table.
Fixing the editor and composer module code to create pre-filled nsIControllerCommandTables as services, and the controller constructors to create singleton command tables with do_GetService.
