Added ability to override built-in actions for the editor

This adds the ability to add overrides for built-in actions (i.e. ui_*) in the editor. Also added a number of additional built-in actions for various text-related actions, gui-generic actions (like copy and paste) and graph-related actions (duplicate nodes), etc. Moved the definition of input actions to input_map, rather than in project_settings so the editor can make use of these actions as well.
