main changes are:
- add a new dep on py-requests
- undo the no longer needed iftex.sty workaround
- move MODPY variables to more standard location
- regen plist
Unfortunately py-sphinx changed the suffix from .txt to .rst.txt in the
1.5 series. This means we have to update PLISTs for about 20+ ports as
a result of this version update. Hopefully future updates of py-sphinx
won't be quite as involved.
