Added new example : pretty prints the result of glibtop_*. Work in

* .cvsignore:
	* Makefile.am:
	* pprint.c: (pprint_get_cpu), (pprint_get_fsusage),
	(pprint_get_loadavg), (pprint_get_mem), (pprint_get_mountlist),
	(pprint_get_msg_limits), (main): Added new example : pretty prints
	the result of glibtop_*. Work in progress.

	Now builds procargs.

	* ../configure.in: Added to static list.
