Fixup curve25519 module

Browse source 
Rename methods on the curve25519 interface to be a bit more high level.
Cleanup emscripten wrapper class, wrap long lines and such. Also add a
grunt task alias for building the emscripten compiled curve
implementation.

* We don't run any tests here, just define an abstract test function
* that excercises our requirements for curve25519 interface, which are
*
* privTopub(privateKey)
* keyPair(privateKey)
* takes a 32-byte private key array buffer and outputs the corresponding
* public key as an array buffer
*
* ECDHE(publicKey, privateKey)
* sharedSecret(publicKey, privateKey)
* computes a shared secret from two curve25519 keys using the given keys
*
* Ed25519Sign(privateKey, message)
* sign(privateKey, message)
* computes a signature for the given message using a private key
*
* Ed25519Verify(publicKey, message, signature)
* verify(publicKey, message, signature)
* verifies a signature for the given message using a public key
