Extension to MiNT 1.09

[Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>]

This patch implements a new command for the config file:

include filename

The purpose should be obvious :-)

It always annoyed be that i had to change many files if i want to
change the configuration of mint. Now i have a single file for the
common setup and various mint.cnf for testing.
