Encoding Ints larger than 32-bits have issues

[Necried]

Elm seems to be able to represent integers above 32-bits. However, using the division (//) operator does not work, which results in incorrect encoding as those rely on division.

For example:

> 99999999999999999999 // 15
-1320856256 : Int

We're going to investigate sending binary data instead of strings, so that would probably help fix this. Although, Elm makes no guarantees for bits 33 through 64 ;)
