I will take a look at this, will take a few days. Sorry for that. 

For the future: you can invoke 

 python setup.py develop

inside a working-copy of the tw.forms package. That will install it into the 
virtualenv & should make it the active tw.forms. If you want to be 100% sure, 
remove the existing tw.forms egg first.

Then you can simply do "hg pull" to pull in the changes I will make over the 
course of the next few days ;)
