Fix syntax highlighting of class definition arguments

[rkiyanchuk]

The puppetDefArguments region incorrectly highlights arguments if they contain functions due to braces in those functions that make the region to end at the first such argument, not at the end of definitions. See the example below:

class profile::dao::aio (
  $yum_baseurl            = hiera('yum::baseurl'),
  $yum_baseurl_deps       = hiera('yum::baseurl_deps'),

  # Comment here
  $debug                  = hiera('debug', false),
) { ... }

Suggested changes handle situations with functions in class definition better and also highlight inline comments.

Please review and feel free to express any concerns, I'll do further improvement to address those.

It took you guys a while to respond: 1.5 years actually. I believe the changes are trivial enough and do not need licensing, I'm not sure if they are actual 1.5 years later though.
