Lists all the datasources for an account via the CLI

This extracts some of the colored logging functionality into some
convenience functions to log directly to the console (stdout) w/o
the usual logging prefixes and flags.  It's intended for console
messages when using grafana commands.

Creates a new account attached to the default admin account for now.

Makes it possible to separate console output from logging output so
command output can be piped to a file cleanly.

Rewrote and redesign how the data source edit views look and work so they conform better to how account views look, removed tabs and put top nav items to add data source etc, made list, edit and new seperate url routes, #1483

Fixed css issue with sidenav not extending to bottom of page when dashboard requires scrolling, #1483

fixes #1481.  correctly escape api_key.key column name

'key' is a reserved word in mysql. So when building a query,
the api-key.key column name needs to be escaped

Worked on playlist mode, hides dashboard controls and dashboard search button, added prev, stop, next icon buttons

added an inital admin settings view, very basic right now only displays all config options in grafana.ini

Configuration file options can now be overriden using environment variables using GF_<SectionName>_<KeyName> syntax, if Section name contains dots in config they are replaced with underscores, and the section name and keyname needs to be all upper case, #1473

Added two columns to user table, email_verified and theme, no used right now but will probably shortly

Small fixes to getting up and running

Fixes a panic: interface conversion: interface is string, not float64
when importing a dashboard that has a non-float ID.

Running "go build" defaults to building a binary named
grafana in the root dir.

Fixed links to user admin views, and backend html routes for user admin edit/create urls, Closes #1451
