Allowing PropertyFileScannerPlugin to scan property files with extensions other than .properties

[hmozaffari]

PropertyFileScannerPlugin only scans files with .properties extension. Some applications may use other extensions like .config for storing properties.

It would be great if accepted extensions of PropertyFileScannerPlugin is configurable and allow multiple extensions:

jqassistant/plugin/java/src/main/java/com/buschmais/jqassistant/plugin/java/impl/scanner/PropertyFileScannerPlugin.java

Line 33 in c4527b2

return path.toLowerCase().endsWith(".properties");

As a work around I have to rename my custom property files to *.properties to be able to feed it to scanner.
