Fix macro param regexp

Fix #436

[freasy]

Thanks for the issue! But if there is no enforced whitespace \s is obsolet. So the correct regex for matching both cases (and the rest) is:
/{%?.*?params\.([A-Za-z_0-9]+)(?:\|(int|string|double))?(?:\|default\('?"?(.*?)"?'?\))?(?:\|(int|string))?.*?%?}/

There everything is covered by .*? since \s* is included in that term.

Please change the PR, so we can merge it.

I've updated it :) You are correct, there's no use for \s* anymore at all!
