Removing postinstall script

If one was to include this as a NPM dependency. The postinstall script
would fail.

Fixes #23
Removing prepublish script

Looks like this is run even on installing the module. There seems to be a large discussion about this problem [here](https://github.com/npm/npm/issues/3059).

From now on just remember to test and compile before any publishing.

Fixes #24
Bumped version.
