Save Lua UI scripts separately
Previously EditorAction and ExitorHook scripts were saved with instant.xml. The were saved with each session and in the config dir (for new sessions). This allowed inconsistent UI setups, especially when loading old sessions that had no or different scripts. Now Editor scripts (actions and hooks) are saved in a dedicated file, session-independently. This goes along with ui_config in general e.g. action-table-columns The scripts are not saved with ui_config file for two reasons: ui_config settings related to built-in ui_config_vars.h, and in the future there may be further indirection like "ui-rc-file". Note: previously loaded editor scripts are lost with this change.
