3.0-M7 released with a security fix

[Jorge Aliss]

Hi,

I just released 3.0-M7 which includes a fix for the host injection attack reported here: https://github.com/jaliss/securesocial/issues/601. There are 2 new properties that were introduced:

- applicationHost: the host of your application. This is mandatory.

- applicationPort: the port of your application. This is optional.

These values are used to compute the URLs users are pointed to within the default RoutesService implementation.

Please upgrade and let me know if you have questions.

Big thanks to Kenny (@platypii) for filing the issue. 

Jorge
