Added GET flag to tell user login has failed
Merge branch 'login-warn_message-fix' into 'master'

Login warn message fix

There was a handler for that already, somehow when BID failed, the flag 'bid_login_failed' was supposed to be passed through GET request, which wasn't so far, so I just added it back to settings.py
Added Portal do Software Publico modifications
Updated SPB logo to beta version.
