midpath: Fix midpath-core and midpath-cldc, add patches.

midpath-core was slightly refactored, and now installs the
configuration files needed which are picked up locally and
can be overriden per-platform. A much more elegant solution,
in my opinion. Two patches were added to midpath-core, one
which changes the default UI colors to a more palatable gray
pallete and one which disables the mouse cursor and enables
key repeating for the SDL backend.

midpath-cldc now builds files libmidpathfile and libmidpathnio
(via --enable-cldc-vm) which are required, at least for a jamvm
+ midpath combo. No harm in installing them anyways.

Configuration files moved around, and two more added, one default
and one for the ben-nanonote.

PR bumbed all around.
