js: change the write access for js class methods

--
* src/ [Connection, Error, Key, Keyring, MEssage, Signature, gpgmejs]:
    Functions and values that are not meant to be overwritten are now
    moved into their constructors, thus eliminating the possibility of
    overwrites after initialization.

* Key: The mode of use (synchronous cached, or async promises) ivs now
  determined at initialization of that Key. The property Key.isAsync
  reflects this state.

* unittests: fixed old Key syntax for testing.

* Message.js isComplete is now a method and not a getter anymore.

* Added some startup tests.
