bugfix release

Add support to search for the whole UID instead of e-mail only.

To enable this new feature call "selectUidByAnyUidPart()":

   final InputStream plainIS = BouncyGPG.decryptAndVerifyStream()
        .withConfig(Configs.keyringConfigFromFilesForRecipient())
        .selectUidByAnyUidPart()  // << here
        .andRequireSignatureFromAllKeys("Sven Sender")
        ...

API CHANGE: Rfc4880KeySelectionStrategy no longer enforces to search
for e-mail only. If you did not use Rfc4880KeySelectionStrategy
directly this will not affect you. ByEMailKeySelectionStrategy provides
the old Rfc4880KeySelectionStrategy behaviour.

Release 2.1.0

Non-breaking changes
 *  Switch to APACHE2.0 license
 *  Encrypt to multiple recipients
 *  Finer grained control over key selection
 *  New maven example
 *  Improved test coverage
 *  Bump to BC 1.59

Still pre-Alpha
 *  Add Concordion spec-test and tutorial
 *  Add website generated with hugo (wip)
 *  Support for key derivation use cases (--> https://github.com/neuhalje/presentation_content-encryption )

Breaking API Changes
 *  PGPHashAlgorithms / PGPSymmetricEncryptionAlgorithms / PGPCompressionAlgorithms: Encapsulate public final fields with getter
 *  Removed ReencryptExplodedZipMultithreaded
 *  Selection of keys was not compliant with RFC 4880. Probably this is non-breaking for most users. Use Pre202KeySelectionStrategy for old behaviour.
