[TextMate] File Types and Icons

[Patrick Burleson]

So I wanted to start associating most of my plain text files to open
in TextMate and I was hit with a big "bummer". It appears that .sql is
not an ending the TextMate developers had thought would be a text file
and thus, I get the blank icon instead of the nice TextMate Text
Document icon.

Is there a way to tell the Finder that I want the TextMate icon no
matter what the file extension?

Thanks,
Patrick

P.S. I'm fairly new on the OS X platform coming from Windows for the
past few years and the OS 7 and 8 before that.
