HTML5 start-up overhaul

 - Implement promise-based JS interface for custom HTML page
   integration
 - Add download progress callback
 - Add progress bar and indeterminate spinner to default HTML page
 - Try downloading files multiple times when failing
 - Get rid of godotfs.js
 - Separate steps for engine initialization, game initialization and game
   start
 - Allow multiple games on one HTML page
 - Substitution placeholders only used in .html file
 - Placeholders renamed: $GODOT_BASE => $GODOT_BASENAME,
   $GODOT_TMEM -> $GODOT_TOTAL_MEMORY
 - Emscripten Module is now Engine.RuntimeEnvironment (no longer a global)
