On the map page, when we search a location and than want to search for
another, we would have to delete letter by letter of the previous search
text.
Now, when we click on the search input to type another search text, the
previous text will be all selected and we can remove everything with
just hitting the backspace once
Fixes an issue where if the js library from maps.googleapis.com failed to load in the <head>, all of our subsequent Angular would completely break.

Note: `bluebird.js` is a new dependency of `angular-google-maps.js`.
