Outdated readme for test_xxx_colors functions

[Micket]

Crayons.test_256_colors(shownumbers::Bool=true)
Crayons.test_24bit_colors(shownumbers::Bool=false)

should probably be codes, but, also, shouldn't include ::Bool unless I'm missing something, and also also, it isn't a named argument anyway so it can't even be named regardless.

Hm,

The shownumbers is not a keyword argument, just a description of the positional argument.

[Micket]

I see, well, the statement

if your terminal supports 256 colors, use Crayons.test_256_colors(shownumbers::Bool=true)

fooled a newbie like me a bit as it kind of looks like a keyword argument.

[KristofferC]

Yeah, I think this exact thing happened before. I guess I would put a semicolon to indicate the start of the keywords. But I could change it to some other syntax if you have a good suggestion. Or perhaps making it an actual keyword argument makes sense.

[KristofferC]

I'll close this for now since I haven't figured out a better way to write it heh.
