* Increase emscripten stack size and decrease path size to fix emscripten builds broken since de45fc2
* use modularize flags for better-behaved javascript output
* makefile and loader changes
* use specialHTMLTargets to support modular access to canvas
* bind key events to canvas, not document
This way focus means focus and we can have multiple RA instances in
one page.
* Work around an emscripten bug in strict mode
* (Emscripten) Use console.error() for error messages
* increase asyncify stack size
* Fix `-lm` flag-related compile warnings in emscripten
