Any number of commands can be added in a frame, from several different sources.
Most commands come from either keybindings or console line input, but remote
servers can also send across commands and entire text files can be execed.

The + command line options are also added to the command buffer.

Command execution takes a null terminated string, breaks it into tokens,
then searches for a command or variable that matches the first token.

Commands can come from three sources, but the handler functions may choose
to disallow the action or forward it to a remote server if the source is
not apropriate.
