Commit: Justin Boffemmyer <flux AT shaolin.homelinux.org>

Improved method for generating base tool-chain

The method for searching for isntalled cache files has received a
large overhaul, with borrowings from sorcery itself. The host triplet
is gathered from the sorcery archspec files corresponding to the value
of $ARCHITECTURE defined in /etc/local/sorcery/config. The version of
the spell to grab the cache tarball for is taken from the version
which is currently installed, by grabbing the last field in
/var/state/sorcery/packages. A function for generating a cache tarball
when one doesn't exist on the host for the corresponding spell still
needs to be implemented though.

Beginning of config file for cauldron

This config file only has some of the configs for cauldron. This will
continue to be fleshed out later. For now it contains the variables
explicitly referenced in the cauldron shell script (which is also
still in development)

commit a0df9bf9ae3151a74ed6488cc5809e659ed21099
Author: Justin Boffemmyer <flux AT shaolin.homelinux.org>

forgot a "function" keyword in installers/common

Forgot to include the "function" keyword for a function in
installers/common.

cauldron and installers/common fixes and formatting

Incorporated various fixes to proactively squash bugs (as well as to
flesh out
the implementations) of both cauldron and installers/common. Additionally,
cleaned up the formatting of both files to use 2 spaces for indentations
instead of tabs, and used the "function" keyword to define functions more
explicitly.
