Various puppet-lint fixes

[mattock]

These two commits fix various warnings reported by puppet-lint.

A lot more warnings were reported, but I did not fix them yet. For example:

• Wrong indentation in resource / class definitions
• Two-space soft tabs
• Undocumented defines
• Trailing whitespace

The indentation thing was the biggest complaint. Puppet-lint wants resources/classes to be called like this:

class { '::foo':
    param           => 'somevalue',
    long_param_name => 'somevalue',
}

In case the formatting gets messed up, the arrows are supposed to be aligned on top of each either.

If you want, I can fix most of the remaining warnings too and send another pull request.

Best regards,

Samuli
