Modernized app UI

[tvrzna]

Hello, I'd like to share with modernized UI, which I've been making last 3 weeks.

Features

• Dashboard splitted into single pages.
• New logo & favicon
• FontAwesome replaced by subset generated on fontello.com (config file at 'flux/fontello-config.json')
• Dashboard shows last 10 builds from any repository.
• Added paging into Repository builds.
• New confirmation dialog by attribute 'data-confirmation'.
• Custom error pages; 404 and 403 look like part of app.
• On Add User checking username and password to not be empty.
• User could not remove own account.
• Autorefresh on running build page every 5 seconds.

Screenshots

Since picture can say more than thousand words, here are screenshots:

Login	Dashboard	Repositories	Repository Overview	Build overview
Users	User Settings	Integration	Confirmation	Logo

Hey @tvrzna, sorry for the lack of response so far.

Thanks a lot for this PR, your changes look really cool! I'll have a closer look in the coming days and will most likely merge it afterwards! 😃
