Title: Ignore singular curly brackets in template parser

By some reason Liquid parser currently don't allow to use curly brackets
inside of {{ }}.

``` liquid
{{ 'hello {world}' }}
```

This will cause syntax error.
I don't know what was a reason for this limitation.
There is no test case covering this behavior so I think we can fix
that.
