#0Af7 => 7700AAff

Convert CSS hex color to AM-compatible color. "#" can be omitted. Alpha channel can also be omitted. This is intended to be embedded in flows (without dialog-blocks)

How it works (algorithm):
1. Trim spaces, and remove optional "#".
2. Expand shorthand notation (if short).
3. Move last 2 nibbles to the start, if they are alpha. This is also known as a "circular shift" or "string rotation".

Regex dotall flag and possessive quantifiers are only used for performance.
