Changed visibility of method getPermissions from protected to public

[feulf]

This change is useful to call getPermission() directly and get the list of permissions for a user, especially if the service who's asking for the permission doesn't have access to the list of allowed permission.

Hey @RainPHP, I've officially got approval from @driesvints to fork this project since it's unmaintained anymore. Please send your pull-request here: https://github.com/saada/lock/pulls

Hey there @saada
What do you mean by officially?

[driesvints]

@RainPHP @saada I said you could fork it, Lock will still officially stay here but you can definitely maintain a fork of it so people can get new features and bug fixes through it.
