Minimal kpathsea support

[Carsten Block]

Hello,
I have done a small patch which adds support for kpathsea to lilypond.
Just have a look at it.

Problem:
* I don't know much about autoconf. So I have changed line 9 in
  config.make manually to 
    USER_LDFLAGS =   -L/usr/lib -lguile -lqthreads -ldl -lm -lkpathsea
  Perhaps someone can add a check to the configure script.

Greetings
Carsten
