Update python2-django-extensions to version 1.4.4
Update python-django-extensions to version 1.4.4
Update osmconvert and osmfilter

Update packages to version 0.8A and 1.3A respectively. Bump epoch for each
package to 2, as this change is considered a versioning decrement. This makes
sense when you consider that version 0.8ALPHA comes before 0.8.

Not shown in this commit: email the author with a request to change the
versioning scheme.
Update mkgmap to version 3337
Use libgroove.pc from source code

Drop the `libgroove.pc` file from the libgroove package. Instead of shipping a
pkg-config config file with the package itself, use the pkg-config file provided
in the source code. This change makes it less likely that the pkg-config config
file and package itself will advertise different versions, and it makes the
pkg-config config file more likely to stay up-to-date with upstream.
