Bug when package name has a dash

[paulie4]

Pyramid's .ini scaffolds have use = egg:{{project}} in them, but cornice/scaffolds/cornice/+package+.ini_tmpl has use = egg:{{package}}. This creates a .ini file with an incorrect egg reference, which causes a pkg_resources.DistributionNotFound exception when pserve is run. I've tested that replacing {{package}} with {{project}} does fix this issue, and I can only assume that nothing else will break with this change.
