David Majda bdf91b5941 Replace "var" with "let" & "const"
This is purely a mechanical change, not taking advantage of block scope
of "let" and "const". Minimizing variable scope will come in the next
commit.

In general, "var" is converted into "let" and "const" is used only for
immutable variables of permanent character (generally spelled in
ALL_CAPS). Using it for any immutable variable regardless on its
permanence would feel confusing.

Any code which is not transpiled and needs to run in ES6 environment
(examples, code in grammars embedded in specs, ...) is kept unchanged.
This is also true for code generated by PEG.js.

David Majda 5c40fff136 Pass spec code through Babel before serving it to the browser
This will allow to use ES2015 constructs in spec code.

The change required introducing a small server, which serves both PEG.js
and spec code passed through Babel and bundled together. This allowed to
convert the specs to regular modules and get rid of the hackery that was
previously needed to make them run both in Node.js and in the browser.

Note the specs no longer exercise the browser version. This will allow
to spec PEG.js internals in the future.

See #442.
