v0.0.26

Added new notA and notAn methods, so you can now check for the absence of roles:

Bouncer::is($user)->notA('moderator');
Bouncer::is($user)->notAn('editor');

Also added the isNot method to the user trait:

$user->isNot('admin');

Fixes:

• Model names weren't being passed through properly in the user trait's allow and disallow methods. dcfd741
• Model abilities were sometimes being conflated. fe480de
