Latest changes from Sergey

After exchanging many mails with Martin Vala, I prepared JS code which can be really inserted into arbitrary HTML page.
At least Martin was managing to run his test server http://alicepc104.jinr.ru/ with such code.

Together with these small changes I did several more improvements:
- migration to d3.v3.js and jQuery v2.1.1
- fix errors in histograms statistic filling
- possibility of move and resize of statbox
- remove many (not all) global variables
- example.htm with direct usage JSRootIO graphics  (like Martin did)

- example of inserting ROOT graphics from THttpServer into <iframe></iframe>
