parse_color: return success + drop fallback color
This is the first in a series of commits to refactor the color handling in sway. This changes parse_color to return whether it was success and no longer uses 0xFFFFFFFF as the fallback color. This also verifies that the string actually contains a valid hexadecimal number along with the length checks. In the process of altering the calls to parse_color, I also took the opportunity to heavily refactor swaybar's ipc_parse_colors function. This allowed for several lines of duplicated code to be removed.
