[i18n] Russian locale

[Rashid N. Achilov]

Russian localization in Horde looks very incomplete. Full messages catalog has 
2091 messages, 1219 fuzzy, 563 untranslated. I have started to complete this, 
and re-check ru_RU.po file now. I'll create bug in tracker, where will post 
patch to supplied ru_RU.po file. After patching there will be 907 fuzzy and 
440 untranslated, so I had have translated now 312 fuzzy and 123 untranslated 
messages.

Bug 8642.
