Block for version 5

I was interested in the Diggthis block you have implemented in version 2 for both my D5 and D6 sites. In particular, I have a number of views, which cannot be voted on using the standard 'Content Type' placement. I was dissappointed when I found the feature was excluse to D6.

Playing 'Why Not', as the code does not appear to be version-specific, I copied the D6 code for diggthis_block() and diggthis_button_create() into the D5 module, and it works great! This should be done to 5.x-2.0-rc1 in CVS so the block feature is available in D5.
