Enables users to create custom slash commands with a GUI.
Usage:
/cmdui - Shows the GUI.
/cmdadd - Adds a command. Usage: /cmdadd commandname text
/cmddel - Deletes a command. Usage: /cmddel commandname
/cmdreplace cmdname text
/cmdprint - Lists current commands.
Multiple commands may be specified on the same line; just make sure that each command begins with a forward slash (/), and ends with a semicolon (, even the last command in your list.
Command arguments may be passed to each slash-command too, specify them on the command line, and they'll be replaced in order. In your /cmdadd command text, you may use %1, %2, and so on, which will be replaced. You may also use %t to get the name of your target.");
