Re-consider custom CSS support

[techboyg5]

Initially custom CSS support was declined. However I want to reconsider it because HTCs (which allowed executing JavaScript in CSS) are not supported in Internet Explorer 10+, and were never supported in any other browser.

You can use the data-custom-css attribute on the script to load the custom CSS from a URL.

I too would like @jdanyow to re-consider this idea.

Custom theme would be enough for most of the users, but for others who want more detailed customizations they have to rely on utterances maintainers to merge their themes into official codebase. And this is where all things slow down: they have to wait for the maintainers to review, check the visual effect, merge, and publish to production server every time the theme is modified. Some themes have been sitting for months in the pull requests list, and the waiting still goes on...
