[arch-general] out-of-date python-cheetah, python-formencode

[adam]

python-formencode-0.9 is in AUR as it was needed in order to build a
package depending on it. The old version still exists in supported
branch but would like to have it replaced/upgraded with my PKGBUILD.

python-cheetah is one release old as the package was placed a month
prior to the next release.

These packages haven't be updated in awhile I do not believe

Thanks
