Fixes css list substitution bug

[ghost]

If you had a css list and the last item was a template, then the substituter would incorrectly replace it with $_:_____, thinking it was a full key/value replacement. This was because it didn't search past the beginning of the list to look for the colon (:) character. To fix this, I modified the regex for the previous colon to search anything that isn't a semi-colon or left curly. This way it can find the colon and properly replace with _______.

This addresses an issue I posted: #72

@runem Any plans for a new release? Our team was hoping to integrate the above changes into our tools without having to switch to our fork, but not rush.

Sorry, lately I have been investing my time in the performance refactor branch of lit-analyzer so I haven't come around to finish testing and publish the code on master (30 commits to be published) :-)

However, I have a couple of times been thinking about publishing a new version of master, so now might be the time to do it. You can expect it to be published within a week. I'll keep you updated if the plan changes (the plan could be changed if the tests fail) 👍
