Mark Django REST Framework as incompatible with eggs

[xordoquy]

I just found that sometime Django REST Framework HTML renderer may not work depending on how you install it. In my case, this was listed within a setup.py's install_require which lead Django REST Framework to be installed as an egg.
Django doesn't load templates from eggs by default and has no way to gather the static files from an egg at all.
jezdez & dstuff confirm the way to fix that is to mark the packages as zip_safe = False.

Okay, sure thing. If there's anything online we can link to from this PR with context that'd be helpful.

Also if noted in the release notes, then include it with a more user-facing message (eg. "Ensure templates load correctly when pacakge is installed with easy_install in windows")

Link to relevant docs...

Not all packages, however, are capable of running in compressed form, because they may expect to be able to access either source code or data files as normal operating system files.

In general you probably don’t want your packages to be installed as zip files because some tools do not support them and they make debugging a lot harder.

Including your IRC convo for future reference.

Assume we've never had it raised before because it only manifests on easy_install + windows.

Actually, I had it while pip installing my project which has DRF in the setup's install_requires.

In which case utterly mystifying that it's not been reported previously.

Be interesting to know if there's any design convo around changing the default of this - as a developer I shouldn't have to know about magically keys that I have to set in the config - it really oughta just not be broken in the first place.
