[Enhancement] Added ability to add individual Permissions to User

[vinayakkulkarni]

Basically #800 but with latest base fork (supporting Laravel 5.5)

• Added docblocs which were missing in add user_permission to support user attach permission #800
• Added scopeWithPermission to EntrustUserTrait.php
• Updated README.md

Why?
Let's say I have a user, Joao, he is a reviewer who has x number of permissions defined in a role. But let's say I want Joao to edit other people's reviews too, but to do that, I'd need to add a new Role with additional Permission of editing other people's reviews too which would become chaotic as for each and every different type of permission, I'd need to create a new role.

Take a look at the screens:
Role:

Permission:

This highly increases the functionality of this awesome plugin and I bet the community would appreciate if they had an option to assign individual roles to user instead of creating temp roles for each and every permutation and combination of permissions and roles.

PS. I (might) have to update the README with more detailed example and usage.

PPS. I've not taken a look at the Tests yet, just copy-pasted them from @csi0n PR
