fix(ngdoc): add default values to ngdoc template

ngDoc did not add default value to template, even though it was present
in the documentation. This change adds the default value to the
description column in the parameters table.

fix($location): re-assign location after BFCache back

In the Android browser, the BFCache maintains
the state of JavaScript applications even when
navigating to another app, so that going
forward and back, to and from an application
is very fast.

Unfortunately, this can have undesired side
effects. In this instance, the location
variable was holding a reference to a stale
window.location, and was throwing errors
when going back to an Angular app after
browsing to another site.

This fix makes sure that location.url()
includes a check to make sure that location
is referencing the current window.location.

refactor(select): options regexp simplification

\w matches [a-zA-Z0-9_] and \d matches [0-9], using both in a character set is
simply redundant.
