- Update to 4.0:
* Add apps module - a replacement for pmenu and the default menu
generator from v4.0 (hence major bump)
* Move pmenu and lx modules to contrib/ to make maintenance and
packaging easier.
* jgmenu.c: hide 'last selection border' (issue #103).
* Update man pages and usage() to prefer `jgmenu_run init` over
`jgmenu init`
* Add banned.h to make audits easier
* Add scripts/pbuild to simplify building deb packages with pbuilder.
* Add configure script in order to (a) make contrib/ packages easier
to manange; and (b) remove dependency checking from Makefile
* greeneye: change category 'Games' to 'Game' in order to comply with
freedesktop.org XDG menu-spec.
* filter.c: support case-insensitive non-ASCII search (issue #91)
