Weechat v4.1.0

Highlights:

• New keys to move in cursor mode
• IRC CTCP replies are now evaluated, with the same variables available, so now the syntax is for example ${version} instead of $version
• Two infos to get nick colors have been added: nick_color_ignore_case and nick_color_name_ignore_case.
• A new variable allowed_values has been added in fset options.
