Updated CLI so that it sets the console settings to its liking on getting control, but turns echo back on the console before giving control to a program. Also cleaned up how the COMMAND setting is handled so it should work when a program quits as well.
Updates to get a version of the kernel that can be stored in flash. The data segment is in the first 64KB and may need to be moved. Also, there is some glitching with the line editing routines.
Changes to the system information record to better match the FPGA's registers and to more dynamically determine machine ID, CPU, clock speed, etc. Added clock speed to the record, and removed some fields that may not be useful.
