[R-pkgs] mvbutils and debug: new versions

[Mark.Bravington at csiro.au]

New versions of the 'mvbutils' and 'debug' packages are now available on CRAN. These should work with R 2.10 as well as R 2.9.

'mvbutils' offers tools for organization of workspaces, function/documentation editing with backups, package construction and updating, seamless per-object lazy-loading, and various miscellaneous goodies.

New in this version: nearly-automated package building using only plain-text documentation, plus the ability to edit & update your package while it's loaded, i.e. without needing to reinstall it or to quit R. These new features are "beta level"; they've been tested by me and some colleagues, but are still a bit experimental. Comments welcome.

'debug' is a debugger with: separate code windows; line-numbered conditional breakpoints; continuation on errors; direct interpretation of commands from console; skipping backwards & forwards; handling of 'on.exit'. This version fixes a few minor bugs.
