DuckClient 5.6 released

The next major release is coming along slowly, so I decided to push some of the small quality-of-life fixes out in a minor release.

The single new feature in this version is a new Prefences setting to limit the scrollback buffer length. There's also a fix for character set negotiation (telnet CHARSET), and a tweak to ID newer TinyMUX servers properly. Finally, the Windows version now has a proper installer. I'm still including the ZIP file for Windows, in case you prefer to just unzip it somewhere and run it instead of installing it.

Those of you using ChromeOS should receive the update soon. Those of you running the standalone version will want to grab it from the downloads directory.
