Laravel 5.5 support for console commands

[YannickLauzier]

Here a little fix for Laravel 5.5. :-)

The fire Method
Any fire methods present on your Artisan commands should be renamed to handle.

@hmazter reported the issue.
#40

Thanks ! :-)

Thx for the PR, @YannickLauzier!

The Laravel core devs are really not into semver, are they? 😅

Only concern here: This change will break compatibility with previous Laravel 5.x versions. Maybe we should keep the fire method and just add a handle method, just adding a comment why there are both.

Otherwise we need to create another branch for the 5.5 code.

Decided what to do with this? Maybe having both fire and handle is a good idea for supporting Laravel 5.x

[hmazter]

Having both is how I have solved one of my packages.
