1.20 release - documentation improvements

[Вячеслав Матюхин]

So, I'm back for another period of active ubic development :)

Several people complained about documentation, so 1.20 release brings several improvements.
"perldoc ubic", "perldoc Ubic::Service" and "perldoc Ubic::Result", in particular, are now a bit more detailed.

If you have any major or minor complains about documentation, please let me know.
