Accept colours in uppercase

[hankertrix]

The output of some colouring tools like wallust and pywal is in uppercase, and it seems like swaylock can't parse those colours. I think simply changing the colours to lowercase before parsing would be great to support these tools.

swaylock --color '#FF0000' works fine. What do you mean by "colours in uppercase"?

Sorry for the noise, after more testing I realised colours in uppercase work as well.

There really needs to be more documentation on what is valid for the configuration file. It turns out that colours cannot be strings or be in any kind of quotes in the config file.
