Move to py-bcrypt 0.3 in requirements file.

py-bycrypt 0.2 has security issues and was dropped from PyPI, causing
issues during developer setup when we try to install it. Since our
production instance is already using 0.3 without any issues, this 
updates compiled.txt to point to the newer version (and also removes
the import of funfactory's compiled.txt like our other requirements
already have).
Avoid hitting the cache when create new snippet template variables.
