I guess I am on a roll with these bug fixes, so keep them coming if you got 'em...
#13 - Filter out directories while searching for POM files.
#23 - Add a configuration option to enable/disable the plugin response to POM changes
#21 and #22 - Both related to the file system listener giving events to all open plugin instances (not just the one that caused the event). Fixed this by only responding to changes on POM files from the project being managed by each specific plugin instance.
