Feature/removable files

[mrdj07]

I needed to fix the remove image problem. I had in mind a solution of flattening the fields of the layout in order to let the Deletion Controller do it's job, but this pull request had it laid down pretty nicely.

I based my branch from master, cleaned up some stuff I found unnecessary in the initial PR, then found the following issues and fixed them:

• The Original PR worked to delete the files, tough this was not the correct way of dealing with the model, this way I let Nova know what fields to update and it does the job.
• The FormField did not update the last version timestamp after the deletion of the file, as the original FormFileField does. So I added the needed events to be caught by the FormPanel.
• The Add Layout button was gone: The field limit counter was buggy. Returned a "NaN" when no limit was set. Added validation for both the original dropdown and the searchfield.
• The required Laravel Version was added by previous commits, I added version 8, since this is the version I'm working with, and I've encountered no problems at all.

I also reformatted all of the PHP files in PSR-2.

Hi @mrdj07,

Thanks for your PR ! At first glance, it looks good to me.

You mentioned some issues with the limit counter, could you please check if your PR needs changes since I merged PR #292 (adding some extra limit functionalities) ? Thanks !

[mrdj07]

Seems like the limit issues were indeed fixed.

Though now my PR is in conflict, I'll fix it asap.

@Nyratas Any idea when this PR could get merged?

[mrdj07]

After my lastest merge I had a bad conflict resolution resulting in an infinite loop, it's now fixed.
