Optimize HTML files, fix some mistakes.

Optimize HTML files(HELL YEAH! I did shit again :D) ver. 1.0:
- used jquery
- delete folders /src/main/webapp/eng and /src/main/webapp/rus

In the feature:
- COMMENTS COMMENTS!!
- reuse common blocks of code again (e.g header.html, footer.html)
- take the data directly from the mongoDB(?)
- using google sitemap script for a multilanguage?
