implement uninstall in modmake.rules
add LIBADD_LOCAL var for use in the module makefiles, it both links to the module, and is a dependency like LOCAL_OBJS
fix bug in src/mod/Makefile(.am) that was causing make install to fail on first run for those modules that used the default mod makefile
implement the getlib.sh script in mod_shout Makefile (works.. but still wip)
