Breakthrough:

I've discovered a workaround for Bundler that would support a fork! There are 2 problems:

1. When a plugin gem lists, say, `actionmailer` as a dependency, installing that gem when using a fork would attempt to install `actionmailer`, not use your fork (say, `intrepidmailer`).
2. Even accounting for that, the plugin gem would attempt to `require "actionmailer"`. Oops.

Both solved!
