nbactions.xml must not be ignored (?)
This file as documentation (which seems lacking) states is used for calling custom Maven goals from the IDE.
Ignoring this file was a source much confusion in few projects (mapping Run action to custom goals... etc etc)
Also this file does anything worth ignoring
Added by #145
Exclusion of `nbactions.xml` from `.gitgnore` should be discussed.
