TISTUD-6834 Add F3 command to jump from string keys in i18n files to usage
-  Register a dynamic context based on the editor id for all Aptana/Appcelerator editors. The context generated is the editor id plus the suffix ".context". This allows us to associate keybindings with specific editors (so we can do an F3 binding for JS that is different from the one for xml editors).
