Current state of cls support

Bugs with cls palettes:
Cls palettes that use non-alphanumeric characters in the names of their colors e.g. Japanese, will not parse correctly.

Writing cls is currently not finished. I hope to get this working, though I've still got a lot of investigating to do.

What you can currently do with cls palettes:
You can load cls palettes that do not have named colors, and those that only use alphanumeric characters.

You can convert cls to tpl and gpl.
