Add sysutils/mtm:

mtm is the Micro Terminal Multiplexer, a terminal multiplexer.

It has four major features/princples:

• Simplicity: there are three commands (change focus, split, close). There are no modes, no dozens of commands, no crazy feature list.
• Compatibility: mtm emulates a classic ANSI text terminal. That means it should work out of the box on essentially all terminfo/termcap-based systems (even pretty old ones), without needing to install a new termcap entry.
• Size mtm is small. The entire project is around 1000 lines of code.
• Stability: mtm is "finished" as it is now. You don't need to worry about it changing on you unexpectedly. The only changes that can happen at this point are:
  • Bug fixes.
  • Translation improvements.
  • Accessibility improvements.
  • Fixes to keep it working on modern OSes.
