Title: Make brew search multithreaded

This is the same change as shown in this [pull request](https://github.com/mxcl/homebrew/pull/11742) except without a load of other random commits thrown in by accident. It's also updated with the changes in the repositories (removal of adamv/alt and addition of homebrew/science) since the original was made.

Basically, it runs each call to ```search_tap``` in a different thread, which makes ```brew search``` about 30% faster, which is enough to notice when using it.
