adds imlib2-support to fluxbox: allows us to load several imageformats

besides xpm. to get imlib2 support in fluxbox one has to 
 
  ./configure --enable-imblib2

default is disabled.  a fluxbox-binary that supports imlib2 will have 
IMLIB2 in "fluxbox -info"-output

explanation to the changed files:

 * xft.m4 -> acinclude.m4 + added ac_path_generic.m4 
   (from http://ac-archive.sourceforge.net/Miscellaneous/ac_path_generic.html)

 * configure.in, Makefile.am, src/FbTk/Makefile.am changed to handle
   imlib2-support

 * Font.cc/hh Image.cc/hh App.cc fluxbox.cc consistent way of init for global
   stuff for fonts and imagehandlers.

 * rest of changes just add the imlib2-code, pretty straightforward
