Move templates closer to what handlebars-fluent uses

[Manishearth]

This bring us closer to #946

r? @XAMPPRocky or @skade

Fixes #957

[Manishearth]

After this I think the only work that needs to be done is the actual integration work, the templates are now using the correct format so there won't be much churn.

[Manishearth]

I have verified that stuff is still working after this.

[XAMPPRocky]

@Manishearth This looks good to me! The one question I have is that you also changed all of the arguments from being like fluent community-team to fluent "community-team" is this actually important to the code working or is it a style choice?

[Manishearth]

Yes, it's important to the code working. See alerque/handlebars-helper-fluent#2 , what we used to do was incorrect. This was mentioned in the second line of #957

To be able to switch over to handlebars-fluent we need to make this change as well, the old syntax will not work anymore.

That's fine, I have no preference I just wanted to know for the future.
