[Evolution] Bug#501619: A little punctuation correction

[Al Nikolov]

The patch contains of mostly better IMO stylistics in Russian sentences (less 
English-like straight translations), many punctuation corrections (again, 
less straight English-like commas), several orthographic corrections (mostly 
typos), few new translated strings (there is no more untranslated messages in 
this .po), and few redefined terms.
