Correct FileUploadAction.php class name

[wray-goenergies]

Assuming there is not a reason for the class and file name to differ for this file I propose changing the class name AbstractUploadAction to match the file name FileUploadAction; which will also match the naming conventions of the other action files: FileListAction.php and FileDeleteAction.php.

@wray-goenergies thanks for your contribution. I'll check how that would affect BC and if it does, will merge and publish a major version update

@tonydspaniard the current state of the file does not allow autoloading it, so I do not see a reason to keep current name. The only way to properly use this code is to copy it to your application.

I am for merging this change.

@cebe thanks... you are correct.
