DuckClient 5.8 released

The standalone binaries for DuckClient 5.8 have been released in the downloads directory. The ChromeOS version will be available from the Chrome Web Store as soon as Google approves it. v5.8 fixes a bug in UTF-8 decoding that caused incorrect characters to appear when a multibyte character was split between two network packets. There's also a speculative fix for a similar issue with ANSI escape sequences, and a fix for a bug that caused the Preferences window to not open the first time it was clicked.
