Doing Stuff some people don't seem to care about.

Added Directserial to makefile (else it will not be in the source archive and thus not in the builds)
Enabled it on win32 hosts.
Made it only compilable for win32 target hosts.
dosbox.cpp:
Added help for the configfile for directserial! (Users don't read the source.)
ifdef some more stuff
enable MPU-intelligent-mode by default.
disable Directserial by default.
