Dealing with Infinity, NaN, and the square root of -1. #88

BYOB does not handle special floating point numbers like infinity and NaN well at all. This should be repaired so as not to confuse users. Errors should appear when a division by 0 is attempted, or something else along those lines.

[x] Infinity can be put in the cell attribute maximum.
[x] Sqrt(0 / 0) > 10000000 is true for some reason
[x] Sprites can move to infinity.
[x] Moving to an impossible position causes an error. (Seems to be fixed in newer versions of Snap!)

Could this be another good candidate for a Snap PR?

https://github.com/jmoenig/Snap--Build-Your-Own-Blocks/pull/1060 doesn't seem to be merged. Did you mean to close this @Craxic?
