js: created TestExtension and smaller fixes

--

* Extensions:

  - Moved testapplication to Demoextension
  - Created BrowserTestExtension.
    Includes mocha and chai. For running tests that cannot be run
    outside a WebExtension

  Both Extensions can be found zipped in build/extensions after
  running build_extensions.sh

* Code changes:
  - src/Config: Place for the configuration
  - small fixes raised during testing in Keyring.js, Message.js,
  - src/gpgmejs_openpgpjs.js don't offer direct GpgME object to the
    outside, as it only causes confusion
  - index.js init() now checks the config for validity

* Tests:
  - Reordered tests in test/.
  - Input values are now in a separate file which may be of use for
    bulk testing

* moved the build directory from dist to build
