Title: [Form] Property path, trying to optimize parsing.

I think `preg_match_all` should be faster than numerous calls to `preg_match` but this PR allows special symbols also for second and so on parts of a path. If it's ok, @bschussek, can you check whether the PR makes enough difference to introduce such changes?
