Merge "releases-versioning" with "master"

This branch includes feature:
-> Automated version iteration through pom files using script ReleaseAll;

New terminology for QTaste version will be used now on:
<version>1.2.2-RC6</version> -> <version>1.2.2-SNAPSHOT</version>

Thus, when we feel ready to release version 1.2.2, a tag shall be created in the repository: qtaste-v1.2.2
and next version snapshot will be 1.2.3-SNAPSHOT
