[3/4] [PATCH] start angle (option of circular_progress) is measured in unusual quantities

[Vladimir Testov]

In current state, start angle is measured in "parrots", where 1 "parrot" = 1 / 
256 of full circle.

With simple patch we can set start angle in degrees (which makes no difference 
for the program, but makes configuration to be more user-friendly)


theme.txt:

before:
    start_angle = -64
after:
    start_angle = -90

nothing else is affected
