Add preliminary version of s51, a UI clone of the 8051 emulator. sdcdb provides source-level debugging using the 8051 emulator, s51. By emulating that emulator a the UI level, we should be able to get source debugging right on our target platform. This is just the preliminary structure for the program with most commands not yet implemented.
