Fix issue where the first inserted user is not assigned the 'admin' role

role.

Modifies admin role assignment to check if the inserted user is the
first user based on sorted query using "createdAt".

Originally, the admin role assignment was done onCreateUser before
the user record was inserted into the db.  It assigned the 'admin' role
to a user if no other user existed in the db.  However, with the change
to insertUserDoc, the 'admin' assignment is done AFTER the first user
is inserted and the original query logic (check if any user exists) no
longer applies

Serve Google fonts locally instead of referencing Google servers.

Based on issue #688 advice, used webfont-dl to download roboto font and
modified base stylesheet to reference roboto locally instead of
referencing Google hosted version.

Used webfont-dl with url
http://fonts.googleapis.com/css?family=Roboto:300,400,500,600,700&subset=latin,cyrillic-ext,greek-ext,greek,vietnamese,latin-ext,cyrillic
to download Roboto font to local directory.  Url originally declared in
base.less.

The url requestd 300,400,500,600, and 700, but it looks like only
300,400,500, and 700 are supported.
