Subject: [PATCH] Update powerline-release script to use live ebuild as the
 base

Reasoning: I am going to add man pages support to the live ebuild, but it does
not make sense to add this to the 1.0 ebuild previously used as the base. Since
new features will likely continue to appear in the live ebuild powerline-release
script was modified to do the right thing under new circumstances.
