#509 require SSL flag now works for both git and mercurial.
- check is done at earlies possible stage
- if detected protocol is not https and flag require is there RhodeCode will
return HTTP Error 406: Not Acceptable, before even checking credentials
- removed push_ssl flag from mercurial UI objects since that would duplicate logic
