Attempt to deal with more cases of gems with native components.

This commit adds a rudimentary check for 'unbuilt' gems, so that we can abort
the application load if there are any gems that have native components that
have not yet been built.

The rake task gems:build has now only builds 'unbuilt' gems as a result.

The rake task gems:build:force has been added to deal with cases of incomplete
builds, or any case where you need to force the build of all of your gems.

Changes the gems:build task to get its gem list by parsing directory entries
in vendor/gems, which sidesteps the chicken/egg issues involved with having a
gem unpacked into vendor/gems without before its native bits are compiled.
