Update to Wasmer 1.0.0

It is identical to 0.1.2, just with a better name for the announcement :-].

Added

• New JAR named wasmer-jni-amd64-$(os)-$(version).jar,
• New Memory.buffer() method to retrieve a direct byte buffer view of the memory data (of kind ByteBuffer),
• Update runtime to Wasmer 0.17,
• Added several examples to illustrate the Wasmer JNI library.

Fixed

• Remove Memory.read() and Memory.write(), use Memory.buffer() instead, it's a more standard API, and it fixes an important bug in the Memory API design.

Added

• Publishing packages (JAR) to Bintray.

Changed

• Polishing the code.
• Removing panics.

First release!

This release sets up basic API, with a Module, Instance, Exports, and Memory API.
