[dwm] Patch to handle null X Class the way you want.

I have a number of in-house written X Clients that don't set the X res
class and X res name properties making XGetClassHint return non-zero. I
found that this short circuited the regular expression processing thus
forcing all such clients to the default action vis. floating and/or
tagging. I see this as a bug but you may not.

It so happens that I want these clients to float and my default action
is to tile.

I am submitting the following patch which allows this. If XGetClassHint
returns non zero it sets the test string to "::name" and normal regular
expression processing proceeds. Now you can create a regular expression
like "::.*" and send these clients where you want.

By the way, I've only just tried dwm and I love it even more than wmii.

Cheers,
John
