To be able to achieve the things that we would like to achieve with the
Asterisk GUI project, we need a fully functional HTTP interface with access
to the Asterisk manager interface.  One of the things that was intended to be
a part of this system, but was never actually implemented, was the ability for
the GUI to be able to upload files to Asterisk.  So, this commit adds this in
the most minimally invasive way that we could come up with.

A lot of work on minimime was done by Steve Murphy.  He fixed a lot of bugs in
the parser, and updated it to be thread-safe.  The ability to check
permissions of active manager sessions was added by Dwayne Hubbard.  Then,
hacking this all together and do doing the modifications necessary to the HTTP
interface was done by me.
