Russian translation and other changes 

1. Most strings were translated to Russian. Application name was not translated. "Mother Hen" was translated as "Дополнительная забота" ("Additional care") which sounds stupidly funny. There was a string "Remind users that this program is not locking their device" which was translated like there was no word "users". Also I faced the problem that the buttons in landscape mode are too wide and pattern becomes too small. I do not know how to solve this.

2. help.html and about.html were moved to /res/raw to allow translation
3. Pattern generation code was rewritten and now it generates really random patterns but it works slower (my phone generates 20x20 in 6 seconds when previous code makes it in 1 second)
