Migration to Ember v1.4.0

[petrvolny]

Updated dependency to Ember 1.4.0, Handlebars 1.3.0
Handlebars refactoring:

• bindAttr -> bind-attr
• linkTo -> link-to
• quoted {{action}} names

Relates to #95

[bolshchikov]

Deprecate quoteless action names.

The app code handlebars contains also actions without quotes. Otherwise the app fails on ajax page

@petrvolny, I think it might also worth to move to Handlerbars v1.3

[petrvolny]

Ok, sure. Will fix it soon. Thanks.

[petrvolny]

Hey @bolshchikov , can you please try the latest changes and let me know if you are ok with them?

[azirbel]

Looks good to me - thank you @petrvolny! I'm ready to merge it but will wait a bit to give @bolshchikov some time to weigh in.

I can imagine that @addepar-andy is using this stuff. Can you confirm that it is ok with your usage? Is it breaking something?

[azirbel]

@petrvolny, could you also add the changed dist folder? Looks like we didn't update it in the past couple commits but we should be keeping it up to date with development.

[petrvolny]

@azirbel, done.

I don't think @addepar-andy is using this personally, but it works with Addepar's usage as a whole. I think this is ready to go - merging it in now. Thanks again!
