Subject: [PATCH] Speeds up completion startup

Before this change, completion startup would rebuild ~/.zcompdump each
time a new shell was created.

After this change, completion startup will only rebuild ~/.zcompdump once per
day.

This dramatically speeds up the startup time for Prezto for all but the
first startup of the day.
