Kernel Updated to 3.8.13

Patrick is updating the default kernel stock in Slackware-Current to the latest and last stable kernel update for 3.8.x branch as Greg has stated that Linux Kernel 3.8.x is now EOL'ed unless someone is willing to take this branch into a longterm kernel.

Config files for previous long term stable kernel (3.4.45) is also provided in testing along with the latest stable kernel for 3.9.x branch (3.9.2). Users who prefer to use other kernel version rather than 3.8.x can use the config files to build their own kernel package.
