Add support for `file(line)`, and handle trash at the end

This also improves the patterns anchoring. I could resist to use \v (very-magic).

Not much tested.

Fixes #14 (https://github.com/bogado/file-line/issues/14)

If we're adding more than one reg exp this has to be more generic. I've just added this support.

@bogado Thanks!

I had a local patch to fall back to matching "... line X". Do you think it's useful and should get added to the list of regexps?

I have made a more generic way to add different regular expressions to the filename parser. Check the latest version
