hasPackage() was looking for the string provided as an RE substring in the
manifest, which resulted in a large number of false positives (i.e. libgtkfoo
would match "gtk+").
Rewrite the manifest loader to parse the files into a proper data structure,
change hasPackage to do full string matches, and add hasPackageMatch which does
RE substring matches.
