Enhancement: Region-folding

[Hicsy]

Gday

PR:

My pull-request with the solution can be found here: #43

Proposal:

Other languages generally have regions folding marked by a comment which starts with the work region .
This will then be folded up until the corresponding comment beginning with endregion.

I understand that this might already be implemented elsewhere in your code that i missed, or perhaps it has been left out for a reason (stale request upstream, awaiting official input, awaiting v2 etc etc).
Feel free to ping me if you need any further clarification.

I have provided examples in the Pull Request.

Cheers

Potential minor issue:

If a madman changes their comment indicator this will obviously not be usable by that script.
This is no issue in the upcoming AHKv2 as they removed this dangerous Directive.
