Bump all SlackBuilds scripts.

  I'm going to rebuild all the packages to fix some file ownership issues
  that messes with the standard filesystem permissions.
libkgapi: slackbuild improvements and bump version.

  - Bump version to fix file ownership permissions in the standard filesystem.

  - Fix KDE 4.13 required patch.

  - New method to reliably get source tarball name, sha1 checksum and prepare

Rename all packages in ./sbopkg after my name.

  - SlackBuilds.org makes this request on their FAQ, so I'm get compliant to it.

  - Remove packages already available in the wild.
Add pre-built packages I use in the list.
