"unrestricted" number of custom palettes (#4932)

- allow more than 10 custom palettes - move palettes into CPP file - Fix for minimizing cpal.htm (saves 2k of flash) - shortened names in cpal, saves about 400 bytes of Flash after packing - removed async from common.js loading to prevent errors on page loads if the file is not cached - restricted nubmer of user palettes on ESP8266 to 10 - unrestricted number of user palettes on all other platforms (total max palettes: 256) - added a warning when adding more than 10 palettes to let the user decide to risk it - Bugfixes in palette enumeration, fixed AR palette adding - AR palettes are now also added if there are more than 10 custom palettes Co-authored-by: Blaž Kristan <blaz@kristan-sp.si>
