Gentoo Ebuilds updated

[Thomas Pani]

Hi all,

I've finally managed to update my Gentoo live ebuilds for enblend/
enfuse to use mercurial.
Plus there's an ebuild for Christoph Spiel's -staging branch.

Hence, if you got any bug reports from Gentoo users and want them to
install from svn head / hg tip, and/or try enblend-staging, you can
point them to the instructions at the panotools wiki [1].
