version 0.3.0

enhancements

Moved from MRAN archives for binaries to posit.packagemanager.co
because of the move from MRAN to posit package manager, attempts are made to use archived binary packages for Linux also.
improved messaging in several places
improved error catching in several places
a number of cases that were annoying for users were identified and addressed.
setupOff and setLibPaths enhanced to be fully functioning in a wide diversity of cases.
When setting install = "force" in Require, now only the user-specified packages are forced to be installed; the rest are installed if required, mimicking install.packages
small efficiency gains in many places
(HEAD) is now more robust as a way to keep a package up to date.

several functions now exported, .downloadFileMasterMainAuth, messageVerbose, messageDF as they were deemed useful enough for other packages.

slow assessment of package dependencies on CRAN packages because of stale available.packagesCached() object. Now, catches this condition and refreshes available.packages()
corrected support for multiple repos that each offer the same packages. Now works like install.packages, i.e., first one first.
base packages can now be installed as previous issues about installing them were dealt with.
