Add exclude option on TwigCs after add it in friendsoftwig/twigcs#81

I think we have to wait for the next Tag on friendsoftwig/twigcs before we merge this PR, because the feature is only on Master branch currently 😉 (See friendsoftwig/twigcs#82)

@oallain Thanks for the PR!
We'll wait untill it is released. In the meantime I've added some small improvements on the code.

Looks good @oallain
Let me know once it is available in a stable version of twigcs.

Will a beta version friendsoftwig/twigcs#82 (comment) be okay or do need to use a stable version? Since I have used patch until now and it works fine.

@truls1502 thanks for feedback :)

I rebase this PR and update it with new Task tests with PHPUnit.
It works fine, but i have an error on AppVeyor, which i don't understand (and not on my code changes) :

1. GrumPHPTest\Unit\Linter\Xml\XmlLinterTest::it_should_validate_xml_with_dtd with data set Windows support #5 ('dtd-url-valid.xml', 0, true)
   DOMDocument::load(): php_network_getaddresses: getaddrinfo failed: No such host is known.

Anyone know why?

Thanks for rebasing! Looks like we can merge it in and still keep BC to the older version of the tool, so good to go IMO.
