Title: Sped up rbenv startup times.

Rbenv attempts to rehash EVERY gem on startup time, and for users with a lot of gems, this can slow the terminal down DRAMATICALLY.

Adding `--no-rehash` to the init command can speed up terminal load time dramatically, at the cost of users having to rehash manually more often.

This fixes issue sorin-ionescu/prezto#335
