Hi all,

I've patched the Directory plugin to allow filename filtering.
Now you can do like so:

[% USE d = Directory(somedir,root=someroot) %]
[% d.files.size           %] # maybe 100 files
[% d.files('jpe?g$').size %] # but only 90 jpeg images

This against Template 2.06.  Hopefully not too heinous; it's my first
patch.

-Allen
