Allow customization of the number of CPUs via env var.
Use 'hardening-wrapper' to build Linux binaries.

Doesn't appear to change much in practice.. hrmm..
Include GeoIP file in bundles.

Fixes some EntryNode issues people ran into.
Remove stale geoip file from Mac skeleton.
Update TODO from recent fixes.
Update versions for new Tor and Firefox releases.
Bump package version, too..
