Modules-1458 mod_wsgi package and module name/path

mod_wsgi must be compiled specifically for the python version in use. This change allows apache::mod::wsgi to take a specified package name and module name/path, in order to use a non-default python (i.e. the ones provided by the IUS Community repository, to use newer-than-default python versions on RHEL/CentOS). Behavior is unchanged if the params are left at their defaults.
Agreed. I guess it's a mental block, but I can't figure out a nice way to express what I mean. How about:
"In order to use mod_wsgi from a non-default package, specify the package name and the name of the .so file that it provides."
