Add matthiasmullie/minify CSS & JS minifier filters

[matthiasmullie]

:+1: seems to be one of the best pure-PHP libs I found in 2 days of scouting ...

@matthiasmullie Just a suggestion .. rename the filter to be less generic (ie mmminify or something making it unequivocally the one from Matthias Mullie) .. there is a lot of confusion among tons of poor coded or unmaintained scripts, so having a clear name to individuate a filter is a must IMHO

I agree with @drAlberT about the name. MinifyFilter is too generic (we already have a bunch of too generic names elsewhere, but no need to increase the confusion)

[stof]

please rebase your branch to fix conflicts (I made some changes in the composer.json file which conflict with your patch because it is the sibling line)

Rebased & updated in response to feedback.
