UI ambiguities around rotate and scale

[jywarren]

Default tool: Rotate vs. Rotate+Scale

Currently the default tool with a "rotate" icon in the main index.html demo is Rotate. But Rotate+Scale should be the default - the separate Rotate and Scale tools are for downstream use in this lib: #105

Same icon issue

Both of these use the same icon, which is confusing:

• "toggling between rotate-and-scale and distort"
• "toggle between rotate and distort

Hotkeys

• these should toggle between Rotate+Scale and Distort, not just Rotate
• Naming misleading

82: "_toggleRotateDistort", // r,
68: "_toggleRotateDistort", // d

• delete CAPS hotkey

• delete Isolate hotkeys

• Let's just say as a rule, we don't expose or make available the separated Rotate and Scale tools at all, as they're only for (edited) Publish changes compatible with downstream React wrapper #105 usage, and we /always/ assume the combined RotateAndScale tool.

Part 2:

• fix all hotkey usage for multiple image select. When you have multiple images hitting a hot key does not update the handles on the image you currently have selected
