switching to HWI Auth Bundle
removed parameters.yml from version tracking
modified dist version of parameters.yml
trying to marry FOS User Bundle with HWI OAuth Bundle
facebook working (although with ugly hack to remove hash after redirect), google and yahoo integrated but not tested, traditional login working but no merge between that and provider logins yet
added yahoo id and token to user entity
changed model to enable more easily extending number of auth providers
fixed eager loading of user entity from related identity entity, added twitter bootstrap
