Title: Stop parsing files that contain no OO code but do contain variables that look like OO keywords

Files are ignored if they don't contain any OO keywords in them
ZF2 autoload functions have a $class variable meaning they got parsed

return function ($class) {
static $map;
...
}

The OO keyword regex wasn't including the "$" inside the word boundary.
