@schakrava Travis?? 😄 🎉

[sfranzen]

Yay I failed the first Travis build! 😛 It only checked for Ruby :(

Hmm, my last commit is not the right way. Will probably revert it and instead insert this.options = options || {}.

@sfranzen Since upgrading backbone pretty much effects every part of the UI, can you tell us if/how you've tested this for potential regressions?

[priyaganti]

Hello @sfranzen Thanks for the PR. I have pulled your changes and tested it on my VM but found out that the UI doesn't work as expected.
Here are some of the bugs that I have noticed.

1. The Disks page doesn't display a table. Its a blank section with navbar and sidebar.
   
2. When I click on Create Pool button instead of the form I get an empty page.
3. Disks table inside the resize pool wizard is empty.
   
4. Clicking on submit to start a new scrub or balance doesn't show the table of scrubs and balances.
5. Share resize form works but the changed values are not displayed on the screen.

These are only a few of them and I see a lot more of them. I think it needs some more testing and fixing up.
Please take a look when you get time. Just wanted to give some feedback as I came across this PR. Cheers!

This is expected to take place shortly as we move towards releasing our first v4 "Built on openSUSE" stable version.
