version 1.5

* Added the function to authenticate, allow the user (with edit rights)
to use JSON API core controllers as well. Thanks `necro_txilok` for the
suggestion.
* Updated `generate_auth_cookie` to allow setting up auth cookie for any
required duration. Just provide the `seconds` var with `nonce`,
`username` and `password` to get required cookie. Default time is 14
days.
* Updated `register` to allow disabling notification email to user after
registration. Provide `notify` var with value 'no' while registering and
it won't send email. You must provide `user_pass` var (which is optional
otherwise) to use this because password is sent in the email. Without
`user_pass` var, this won't make sense disablig notification so it
won't.
* Fixed typos in documentation and aded new documentation.
