Search phone numbers and emails.

The search method now also checks phone numbers and email addresses.
However it still doesn't check for them indivdually. This is mainly due

Scraping the whole multiple contact book design, currently these methods
are only commented out, but will be removed after i redesign how this
thing should work.
