Initial support for Forth

[dcsobral]

This is based on the Scala parser, which is actually quite
incorrect -- assumes existence of single-quote strings (which
will cause problem on any file with symbols), doesn't know
multiline strings, doesn't handle nested comments: all of which
made it a pretty good starting point for Forth.

Parsing Forth is impossible, but this will recognize comments,
strings and blank lines on most projects. Tested against FreeBSD
source.

It doesn't recognize .fs files, as that would require disambiguation against f-sharp. Let whoever has .fs Forth files handle this.

Also... can we please have a revised README? The present one has a broken link to issues, and points to another repo altogether as the source repo.

Hi dcsobral,

Thanks for the great patch. I'm actually surprised to discover that we didn't already have Forth support. This is probably the most popular language that we didn't yet support.

I've merged this into the Ohloh production master, but it will take another 2 or 3 weeks before it is deployed to our production website. At that point, we'll have to manually start clean line counts for all of the Forth projects on Ohloh. If there are particular projects you'd like me to count first, just let me know.

I'm sorry the README has fallen out of date. I will spend a few minutes to makes sure that at least the essential bits are correct.

Thanks so much for your help,

Robin

Thanks. My own personal interest is FreeBSD: Forth was the reason I first became a contributor.
