Election for Alexander Dudaev as Committer on Eclipse RCP Testing Tool

Alexander Dudaev is effectively the only person that can dedicate any significant time to support RCPTT project at the moment.

He is doing general maintenance, keeping up with Eclipse compatibility updates, and has fixed some bugs.

With new build infrastructure, contributors has lost access some important Jenkins functions (can't launch builds being the most prominent), leading to necessity to formalize current Alexander's status.
