nermal 1.1.0 adds some largely backwards-compatible features

 *  whitespace is now allowed more consistently in nermal.decrypt(),
    (which breaks namespaces that start with " "; this now throws an
    error). Whitespace is still not emitted by encrypt().
 *  netstrings are now suffixed with ',' in _pad(); _unpad() has not
    changed. This makes it more proper to call them netstrings.
 *  package.json no longer declares nermal private; I will publish it
    to NPM soon.
 *  bugfix: there was a bug when namespaces contained characters
    which were modified by JSON.stringify(); this was detected when
    writing tests and fixed.
 *  more tests were added and the test script was cleaned up.
