Bugfix and Feature Request for 'Game Of Life 2'

[seiselen]

• Bugfix: Mousedraw happens whether or not mouse is down, likely as I was QAD with the implement ⮕ Could fix or keep as-is, since its harmless in dead regions and out-of-bounds (i.e. off-canvas) is already handled.
• Feature Request: And this has been one since Version-1 back years ago ⮕ Do allow for placing 'spaceships' and other (well-)known 'Conway Shapes'; which I suggest realizing via a modified Drag-And-Drop and Tower-Place functionality as-used-in TD-P5JS.
• Supplemental NAT: On the seiselen GH page in my 'Coding Demos' ⮕Do get around to either swapping out the Version-1 entry with this one, xor adding a new entry therebelow for this one, kthxbai!

resolved the 'supplemental NAT' --- though I DO need to add (tooltip-based?) instructions
