v0.3 Blot Graphemes, too!

The marquee feature for v0.3 is support for grapheme clusters in addition to individual code points. Demicode also gained the ability to iterate over grapheme cluster breaks, so that it can validate user input.

For emoji sequences, demicode goes further and makes their names available, including those only published with the CLDR. Furthermore, demicode now displays the age in terms of the Unicode Emoji version, e.g., E0.7. Next, demicode now uses an improved width calculation for emoji, ensuring that they always have double width—unless they are paired with a text variation selector. To enable that functionality, demicode tracks more UCD properties.

Finally, this release enables logging for remote interactions, adds some tests, and performs optional validation of UCD data.
