Add support for ES6 template strings

This requires a bit of bookeeping in the lexer, as we can have
arbitrary expressions inside the ${...}. To make this work, keep
a stack of template states, in which we count the unclosed braces
to match up with the correct closing brace.

Implements support for `...`. Expressions of the type Foo`...`
and Foo()`...` will come in follow-up commits.
