b621ac6a4d Add ROMX RTC driver, c/o Jeff Mazur. 
This is a modified version of the ROMX Real-Time Clock driver. The changes include:

* Converting the source to ca65.

* Integrating with the driver installer framework.

* Adapting the driver to not modify page 2 beyond $220. The ROMX RTC
  firmware writes bytes to $2B0, and the the original driver placed
  temp code at $250. This can conflict with ProDOS applications that
  use page 2, so the driver was reworked to save/restore anything at
  at $2B0.

Other changes:

* Add a util/ source dir, and cricket/date, quit.system and
  pause.system there.

* Pull the "print current date" logic out of clock drivers into driver
  preamble.

46aef091df Have clock/ram drivers print at the bottom of the screen. 
Trying this out. Might not stick with it.

Also added a PAUSE.SYSTEM that just waits a bit, if you want a delay
in your startup sequence to watch the log messages.
