Subject: [PATCH] opkg_manager: add a list of packages to hide

Advanced build system can come up with an impressive list of
(sub-)packages, most of them not really interesting for installation
through the GUI. Add a filter with simple patterns to suppress the
display of those packages.
TODO: this should be made configurable via a run-time config file.
