Rename resources to dist. Eliminate keyring bundle and expose keyring class in openpgp module. Add mochaTest grunt task to run node server-side tests. Add node_pack grunt task to create npm package into dist and install it for testing. Add node_store config property which specifies location of localStorage emulation when using node. Add repository info to package.json. Move util.js to src directory from util since it is the only file there. Rename class properties in openpgp to the new class names.
