Added the errexit bash function
Renamed bash/funtions/errexit to bash/functions/die
Fixed multiple append/prepend bug in bash/functions/path

When appending/prepending multiple (>2) directories to a path,
the 1st dir got appended/prepended once, then the 2nd dir got
appended/prepended multiple times (N-1 times).
Updated bash/functions/die

* Handle --prefix and --inline flags
* When used in an interactive shell, simply return instead of exiting
Added the gentoo/kernel/purge-kernels script to purge unused kernels
Updated the gentoo/kernel/genkernel-cobalt script

* Install symlinks to most recent entries in /boot
* Don't use the real_root= parameter
Removed the admin/network/dynfw-1.0.1.tar.bz2, which had nothing to do here at all
Merge branch 'master' into staging
