Workflow

[HartmannS]

Add github workflow.
PR #17 is required.
Fixes were made in commit 387dc1d, but unfortunately the 'custom-standards/Flyeralarm/Sniffs/File/ExceptionMessageSniff.php:32' contains a bug.
The sniff currently uses 'T_CONSTANT_ENCAPSED_STRING' which are all strings and not only exception messages, as the name of the sniff suggests.
That means this sniff prevents all "." and "!" from occurring in strings.
That also means, the current implemented workflow will fail.

@vukanac can you review this PR and potentially reanimate if it contains something that is not yet covered in #28?

I apologise for force push to the wrong origin!
I did checkout to this PR and I didn't expect that pushing will actually push to HartmannS fork! I didn't check remote ref.
The original work is pushed back, but the PR lost track of the contribution.
In any case, I am thankful for contribution and I'll take some ideas from it to implement into new PR.
With new PR open we can close this PR.
