Proposal: multiple turtles

[Bojidar Marinov]

Sometimes it is fun to have multiple turtles draw on the screen. Especially when you feel like watching a turtle race 😃 .
It would be nice to support some of the commands from, e.g., FMS logo:

• SETTURTLE n [ownPenSettings] - chooses which turtle should be running. Might have an optional parameter for whether the turtle should share its pen settings
• TURTLE - returns the index of the current turtle
• HASOWNPENP - returns whether the turtle has separate pen settings
• TURTLES - returns the maximal index passed to setturtle since clearscreen. Effectively a count of how many turtles are in use
• BITMAPTURTLE - makes the turtle stamp a bitmap, should be likely ignored for now.
• NOBITMAPTURTLE - disables bitmapturtle, should be likely ignored for now.
• SETTURTLEMODE mode - sets some drawing mode for the bitmap, such as XOR, should be likely ignored for now.
• TURTLEMODE - getter for setturtlemode, should be likely ignored for now.
• ASK n instructions - runs instructions as turtle n

Sounds like a good addition!

Hopefully you're thinking of implementing it since I won't get to it soon. If so, I really appreciate the proposal first. Happy to review changes.

Had a busy weeks month (because of fosdem and other things), and I would try doing something about it this or the next week 😃
