Porteus 5.0

Team Porteus is finally able to announce the immediate availability of Porteus 5.0 final in eight desktop flavours. Main changes include: Linux kernel 5.18.8; Core is based on Slackware 15.0; Perl has been moved to 05-devel; Slackware package managers included slackpkg (in core) and slpkg (in 05-devel); a simple wrapper for slackpkg, pmod, to produce a module of the package; a small script, pkginfo, to provide some info about whether a package is installed, what's in it, whether it has missing libraries and which module it's in, if any; numerous tweaks, fixes and optimizations to our core scripts.
