[1024] [1029] Fixes back button when interest dialog is open

[shreydesai]

1024 - The back button is now disabled when the interest dialog is open

1029 - This problem was caused by the back button not working when the interest dialog was open, but this should not be a concern anymore since the back button will be disabled altogether

This work pretty well, although I couldn't test the location page's back button because of the newly discovered #1066.

One thing I would add with regard to #1024: Can you grey out the BACK button like the rest of the screen to signal to the user that it's unavailable?

I fixed the additional request to #1024.

It looks like the jQuery selectors for Polymer elements tend to differ between iOS/OSX, but it's all fine now. I also remembered to run polybuild.sh, but you can double check. I took a look at #1066 and it definitely seems like a problem. I'll try working on it so that the BACK button appears and then maybe you can re-evaluate this pull request.

Back button is still in the foreground on the company page (the one with images).

Click "Company Information" or the company images above to get to what I'm calling the company page:

New changes:

• Fixed BACK button on the company info and location pages
• Fixed bug where BACK button is automatically disabled before the modal shows up

Issue #1066 is still rampant, so I will fix that next.

Lookin' good!
