v0.5.1

• When a domain name resolves to multiple IP addresses tiny now tries connecting to the rest of the addresses when one fails (#144).
• Fixed a bug introduced in 0.5.0 where the client did not update its internal state after changing nick, causing TUI and client state disagreeing on what the current nick is (#149, introduced with #138).
• tiny no longer needs a 'hostname' field in servers in the config file (#150).
• Version requests are now shown in the server tab if a tab for the requester does not exist (#145).
• Fixed a bug where we forgot to reset "nick accepted" state on disconnect, causing incorrect nick selection when reconnecting (introduced with #138).
• Fixed a bug that caused the client to loop when the connection is closed on the remote end (#153, another bug introduced with #138).
• tiny now uses $XDG_CONFIG_HOME/tiny/config.yml for the default config file location. The old location $HOME/.tinyrc.yml is still used when there isn't a config file in the new location, to avoid breakage. $HOME/.config is used for $XDG_CONFIG_HOME when the env variable is not available (#152).
• Fixed a panic when some clients return later than TUI when exiting tiny.
