New ps3-sources-2.6.23-1 ebuild

With the help of phreak, a fellow Gentoo developer, we now have a new kernel sources ebuild in the Cell overlay. I was having trouble with the kernel eclass, patching, and portage together with revisions. So when a new patch came out, I was adding it to the current one and users had trouble keeping the revisions straight. This is where phreak's ebuild foo was strong. Thanks again.

To our PS3 users, I will now rev bump the ebuilds when a new patch is applied to our sources.

Peace
