Gemfile update
Fixed ampersand in title

If contact title contained an ampersand (John & Jane Doe), it would be
transliterated to &amp;. Used sanitize directly to clean input and then
set as html_safe. Sanitize does not transliterate ampersands.
Smaller fonts

Tightened up font display a bit. Based on 14px instead of 16px.
Contact search form

Renamed search field in top bar to "Quick search…". Added "Search" to
Top Bar. Search brings up Contact Search form with helpers for AND, OR,
and NOT searches. Also specific field searches for phone, email, city,
state, country.
