[mapguide-internals] MIME type for MapGuide packages

That won't work.
IE uses "MIME sniffing" meaning that it reads the first few bytes of the
file, and sees that it is
a zip file, and then disregards all other indicators, like mime headers,
It even has a special security bug due to this (also explains how it works):
Instead, I propose that the MapGuide server looks for both .mpg and .zip
files in the packages folder.

> I'm OK with either solution, but would like feedback so that we can either proceed with the registration or with documenting the preferred solution on the wiki. Once I get some feedback, I'll take care of the registration (if required), having the OSGeo download server configured to implement the chosen solution, and documenting the chosen approach on the wiki.
