Just minor corrections in this release:
1. Ensure HTML5 code doesn't fail when attempting to test whether a sprite has collided with an empty sprite category.
2. Fix a typo in the scrollSpriteIntoView HTML5 function.
3. Fix code generator to not have errors when a disabled rule function has no function assigned (if/end if nesting error).
I'm releasing this now because I just migrated the projects in the project listing
to a new extension in Joomla, and as part of that, I upgraded a few projects to make sure they work easily under the latest release. One of the projects (TDK Remake) exposed a bug in 2.2.2 (#3 above) which I wanted to fix right away so that anybody wanting to work with that sample would be able to do so easily.
