[MRRESOURCES-102] Filtering of non-.vm files

**[Falko Modler](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=famod)** opened **[MRRESOURCES-102](https://issues.apache.org/jira/browse/MRRESOURCES-102?redirect=false)** and commented

It would be a very welcomed addition if the plugin would also filter non-verlocity (.vm) files.

Renaming the files in question to *.vm is not an option for me because:
- MRRESOURCES-94
- the module _providing_ the file(s) also needs them _without_ .vm suffix (fixing this would require some other plugin)
