Small fix from HybridAuth repository
Version 1.2.1 prerelease.

- It was decieded to move `HybridAuth` config file to the yii's config diretory and rename to `hoauth.php`. Extension will try to do it automatically, when config diretory is not writable, it will run with config file from old directory, but old directory has the deprecated status.
- fixed bug with to long username, when registering user for `yii-user` extension.
- Support of login from social networks, that returning no email (also added `HUserInfoForm` class).
- updates in installation instructions
