- added new plugin to test if fnis needs to be run

- some functionality to the plugin interface to enable them to search for files&directories in the virtual FS (rudimentary atm)
- functionality for plugins to react to application being started from MO
- broken ESPs are no longer reported as popup windows but only in the log file
- bugfix: plugins couldn't store persistent data if they had no user-editable settings
