Added datadir and mandir for systems that use different directory trees
In Haiku we don't have share/ at the usual prefix, and man pages are in
documentation/man/... So we need to pass those to configure.
This patch adds --datadir and --mandir support, the autofools way.
* Fix hardcoded -ldl and -lm in the Makefile
* BeOS does not have -lm (it's part of libroot)
* Add Haiku GUI driver haiku.cpp
* Add helper script haiku-pe2qe.sh to clone color settings from Pe to Qemacs
