[gentoo-soc] [Report 13] layman improvements

[Devan Franchini]

Hello all,

This (last) week, the following has been accomplished:

1.) All previous pull-requests have been pulled:
     - This includes the following features:
       * layman-overlay-maker utility script.
       * layman-mounter utility.
       * Squashfs overlay support.
       * Portage Sync Plug-in.
       * Modular overlay types.
       * etc.
2.) Documentation changes:
     - In preparation for a new release, layman's
       version, layman,cfg, and man pages have
       all been changed to reflect the newest
       improvements to layman.
3.) G-Common overlay support removed:
     - It was discussed with the #gentoo-science
       community that g-common was no longer
       in use. So in favor of having it's successor,
       g-sorcery supported, we removed the un-used
       overlay type.
4.) Modular configuration types:
     - Aside from the make.conf and repos.conf
       repo configuration files, the modular plug-in
       system has been implemented to allow users
       to add more repo config options by simply adding
       the config plug-in to the config_modules dir in layman's
       codebase locally.
     - This also allows for maintaining the config types more
       simple.
5.) Code Refining:
     - The layman-9999 ebuild has been modified to reflect
       the improvements to layman and allow users to test
       the current features before it becomes a new release.
     - Some things have been changed to remove found bugs
       reported by users running the live ebuild.

It's been an absolute pleasure working on this project over the course of
the program and I personally am extremely pleased with how it turned out.

I look forward to lending my hand with layman in the future as well so I can
further contribute to the awesome Gentoo community.

With regards,
