[arch-dev-public] pkgstats and repo cleanup

[Allan McRae]

I have now removed most packages that have less that 1% usage and no 
maintainer from the repos, the exceptions being pacbuild and libnids 
(required by something in community).  They are now moving to the AUR, 
but some may take slightly longer to get uploaded due to their PKGBUILDs 
not being updated in a long time and AUR being pedantic (no license, no 
md5sums, no url, etc).
