Todo-tree: Warning about HTML colours

[emanuelenardi]

This warning is displayed about the HTML colours as being invalid

but they are correctly displayed in the editor

It's because the name check is case sensitive and it expects them to be all lower case at the moment.

You can get rid of the warning by changing them to lowercase - I'll make the check case insensitive in the next release.

Thanks for the quick reply!

Should no longer generate the warning in version 0.0.206
