Selenium report improvements

[GoogleCodeExporter]

1) slashes in URL are OS dependent there on linux systems invalid -> URLs 
should have always / slashes
2) test reports should be stored in UTF-8 format
3) asserts aren't logged in reports
4) actions aren't looged too
5) in case of runtime exception (other than selenium exception) the test is 
green and exception is not logged
