0.1:
This is a first release.

0.2:
Fixed blue LED drive in serial.c send_colors() from 'len = strlen(temp) - 1' to 'len = strlen(temp)'.

0.3:
Added universal send_command() in serial.c
removed old send_colors() command.
Added 'save settings' button (sends command 'SLF').
Added help menu.

0.4:
New icon
Added gamma correction, and gamma corection button.

0.5:
Added color selection circle, saturation selection slider, status display.
Added save_settings() for complete GUI.
Note that the color circle plus associated sliders is a completely different interface
from the color selection browser and associated sliders.

0.6:
Fixed status report in send_selected_color_saturation_brightnesss() so it prints reverse_gamma.
Added clock and timers to col.asm, see col.asm for list of changes.
Added fast mode for color sequencing to col.asm.
Added clock calibration to col.asm.

0.7:
Only asm file was changed.
Fixed bug hanging in continuous help print, fixed eeprom programming errors bug,
moved those routines into the interrupt handler, added some banksels, removed offset in
save_status and load_status, so w register has no longer influence.


0.7.1:
Changes in col.asm:
Added limited number of retries and timeouts in eeprom_write.
Disabled interrupt disabling in eeprom_write.
This all likely needed because of some error in the PIC itself, every now and then data errors programming the EEPROM
Still seems to hang sometimes, but better now.

0.7.2:
In col_pic xwindows program added support for UDP control using netcat for the ethernet version of col_pic.
