[Dev] libretools 20140106 release announcement

[Luke T. Shumaker]

I just pushed libretools 20140106.1 to [libre].  It has a couple of
exciting new features.  Be sure to merge your .pacnew files!

How `librefetch` works has changed--it is still compatible with
PKGBUILDs written for the old version, but that behavior is
discouraged.  Now, instead of using a special `libre://` URL, just use
a URL starting with `https://repo.parabolagnulinux.org/other/`!  This
change required changes to librefetch.conf and makepkg.conf--most
users won't have customizations in librefetch.conf, and the
post_install script should take care of your makepkg.conf.

To top that off, `librestage`/`librerelease` now also upload source
files generated by `librefetch`.  To support this, `librerelease` no
longer removed non-package files found in your staging directory. 

Between those two changes, building a package with "custom" source
tarballs doesn't have to be a pain anymore.  Write your mksource() or
SRCBUILD, and run `makepkg -g` just like for any other package; there
are no extra commands to run.

About the librefetch change: Please have the source files follow one
of these formats:
 - `other/$pkgbase/$pkgbase-$pkgver.tar.gz`
 - `other/~yourname/$pkgbase/$pkgbase-$pkgver.tar.gz` (for personal repos)
