Title: added ProcessActiveCheck

This one checks whether a process with a given phrase is active on the server. Might be very useful for checking whether a gameserver has crashed for example.

I am not sure about security issues regarding the exec statement and the $this->command variable. As this directly comes from the services file I think this should be no problem, but I am not a security expert.
Using exec in general could also be a problem (for example on shared hostings), but in a bundle which shall care about the system's health I think it's necessary to do some system-near checks anyway.
