Title: Add code to allow pre fpath entries via zstyle.

I want to add the home-brew zsh/site-packages path to the front of fpath so that any completion functions there will have precedent over the ones in prezto. This patch allows doing this via a zstyle setup in the .zshrc file before prezto is sourced.
