Relative partials aren't working after r.js build

After build, the partials index contains all the templates by their full path
The {{> ./ralatievpath }} complied to a relative and not full path

``` js
this.invokePartial(partials['./ralatievpath'])
```

And you get "The partial ./ralatievpath could not be found" error

I'm on the master code last commit 1837ba90ced022472169d0011da4197b9e9ac4cc

Until it fixed, maybe add a notice about it?
