Updated for 0.17.1 release

This ensures that any header lines sent before the identification
string do not break the identification parsing if they are longer
than the identification string should be.

-SSHJ 0.11.0 (No date set yet)::
+SSHJ 0.17.1 (2016-07-06)::
+* Improved parsing of the SSH Server identification. Too long header lines now no longer break the protocol.
+SSHJ 0.17.0 (2016-07-05)::
+* *Introduced breaking change in SFTP copy behaviour*: Previously an SFTP copy operation would behave differently if both source and target were folders with different names.
+  In this case instead of copying the contents of the source into the target directory, the directory itself was copied as a sub directory of the target directory.
+  This behaviour has been removed in favour of the default behaviour which is to copy the contents of the source into the target. Bringing the behaviour in line with how SCP works.
+* Fixed https://github.com/hierynomus/sshj/issues/252[#252] (via: https://github.com/hierynomus/sshj/pulls/253[#253]): Same name subdirs are no longer merged by accident
+SSHJ 0.16.0 (2016-04-11)::
+* Fixed https://github.com/hierynomus/sshj/issues/239[#239]: Remote port forwards did not work if you used the empty string as address, or a catch-all address.
+* Fixed https://github.com/hierynomus/sshj/issues/242[#242]: Added OSGI headers to sources jar manifest
+* Fixed https://github.com/hierynomus/sshj/issues/236[#236]: Remote Port forwarding with dynamic port allocation fails with BufferUnderflowException
+* Upgraded gradle distribution to 2.12
+* Closed https://github.com/hierynomus/sshj/issues/234[#234]: Dropped Java6 support (0.15.0 was already Java6 incompatible due to Java7 dependency)
+* Fixed https://github.com/hierynomus/sshj/issues/118[#118]: Added configuration switch for waiting on a server ident before sending the client ident.
+* Fixed https://github.com/hierynomus/sshj/issues/114[#114]: Added javadoc that you always need to call close() on a Command before inspecting the exit codes.
+* Fixed https://github.com/hierynomus/sshj/issues/237[#237]: Fixed race condition if a `hostkeys-00@openssh.com` global request is received directly after a successful auth.
+SSHJ 0.15.0 (2015-11-20)::
+* Fixed https://github.com/hierynomus/sshj/issues/220[#220]: Added support for `ssh-ed25519` host keys
+* Fixed https://github.com/hierynomus/sshj/issues/225[#225]: Fixed bug in ECDSA fingerprint calculation that sometimes produced an incorrect fingerprint
+* Added `arcfour` Stream Ciphers from RFC4253 and RFC4345
+* Added all Block Ciphers from RFC4344 and RFC4253
+SSHJ 0.14.0 (2015-11-04)::
+* Fixed https://github.com/hierynomus/sshj/issues/171[#171]: Added support for `curve25519-sha256@libssh.org` key exchange algorithm

+* Fixed https://github.com/hierynomus/sshj/issues/167[#167]: Added support for `diffie-hellman-group-exchange-sha1` and `diffie-hellman-group-exchange-sha256` key exchange methods
+* Fixed https://github.com/hierynomus/sshj/issues/212[#212]: Configure path escaping to enable shell expansion to work correctly
+* Merged https://github.com/hierynomus/sshj/issues/210[#210]: RemoteFileInputStream.skip returns wrong value (Fixes https://github.com/hierynomus/sshj/issues/209[#209])
+* Merged https://github.com/hierynomus/sshj/issues/208[#208]: Added SCP bandwidth limitation support
