Change boot methods to match Eloquent boot[traitName] pattern.

[KKSzymanowski]

Because methods of traits used by the one class cannot have the same name there is a chance that(especially in User model) when using some other trait, it also implements boot method.

To avoid that I changed all boot methods to match Laravel Eloquent boot[traitName] pattern.
It is automatically resolved so it acts exactly like a boot method. Also, you don't need to call parent::boot(actually you mustn't because it will crash everything) and most importantly it keeps you safe from method name conflicts.

I think this issue was raised in Zizaco/Entrust package but never addressed, so I'm doing this here.

I also added composer.lock file to .gitignore because who needs it.

Really looking forward to working with your fork.
