Patch to oaf.m4

[Ronen Tzur <rtzur shani net>]

Hello.

I think there is a need to standardize and simplify the installation
of type=exe components.  Choosing between installing it on the PATH,
or installing it outside the path (requires handling expansion of
variables in oaf.in files) -- and then, to which path -- makes the
whole thing very messy.

I propose adding two small autoconf and automake macros to
"oaf.m4" that help do all of that.

The autoconf macro is AM_OAF_MAKE_RULES which expands to the
definition of two Makefile rules and two automake directory
targets.

The first make rule is OAF_MAKE_OAFIN_RULE, which expands a few
environment variable references in .oaf.in.in files, outputting
to .oaf.in. files.  The xml-i18n-tools package would then
translate .oaf.in into .oaf files, but if you don't use it,
there's an OAF_MAKE_OAF_RULE that will simply copy it.

The automake directory targets are "objdir" and "oafdir",
such that you can have "obj_PROGRAMS=mycomponent" and
"oaf_DATA=MyOafFile.oaf".  And these default to
"{prefix}/lib/bonobo/components" for objdir, and
"{prefix}/share/oaf" for oafdir.

I'm attaching the patch to implement these additions, please
consider applying it.
