Note many additional symbol options for tools

- "🧯" might be a new best Airbrush symbol
- "𝐴" appears closer to MS Paint's Text icon, although it's not centered like the wide character "Ａ"
- "⬙﹅" is quite a nice two-glyph Fill With Color icon, only a bit disjoint with the bucket being too small/low (as I see it rendered)
- Add lasso-themed Free-Form Select symbol alternatives
- Add many misc. options
- Combine composite brush symbols so they're directly visualized ("▭⋹ 𝈸⋹ ⊏⋹ ⸦⋹ ⊂⋹" instead of "▭/𝈸/⊏/⸦/⊂+⋹")
- Add one crosshair cursor option
- Remove "whilst" phrase that didn't add any meaning

 The default symbols used may not be the best on your particular system, so I may add some kind of configuration for this in the future.
 
 ### Cursor
 
-A crosshair cursor could use one of `+✜✛⊹✚╋╬⁘⁛⌖⯐`, but whilst that imitates the look, it might be better to show the pixel under the cursor, i.e. character cell, surrounded by dashes, like this:
