Added docBlock annotations to assist with IDE auto complete for Actions

[travisaustin]

This PR adds docBlocks to several Laravel Actions traits. The docBlocks are intended to help provide better autocompletion when using a PHP IDE. Created for use with PhpStorm, but I suspect it will help users of other IDEs as well.

This PR has no code-changes. The only changes is within comments (docBlocks).

Thanks!

@Wulfheart just to double check, would this interfere with your IDE helper package or is it okay to merge?

I use @Wulfheart 's IDE completion, and I don't expect my PR will affect his package.

My PR helps when writing the action itself. For example, once you've added the AsAction trait, my PR will help your IDE know that you can add properties like jobTimeout and methods like configureJob.

The @Wulfheart package helps provide auto-complete when working outside of the action. For example, when dispatching an Action, the @Wulfheart package helps the IDE know what arguments should be sent to the ::dispatch() method.

Thanks for considering this addition. I hope my understand is correct and that this will work alongside @Wulfheart.

@travisaustin I guess I should start communicating that I don't have any idea how this package works anymore. Would love to find another maintainer.

@Wulfheart I, for one, find your package useful and helpful. So thanks for the work even if it's abandoned.
