Update bam_strings.xml

Unfortunately, I was not able to break the codes into categories, but I think you do it yourself. So I put the text as it looks after decompiling application - res \ values-ru \ strings.xml.

- Added and translated into Russian missing Components 
- All translated into Russian, except for service information 
- Changed meanings translate text, given the length of sentences - that is as short as possible. 
- Fixed grammatical errors translation
