Fix with tests.  Chose to add .01f as hack.  Do we want genuine rounding?

> I realize that FuzzyQuery.floatToEdits is deprecated, but I'd like to make a small fix for posterity.  Because of floating point issues, if a percentage leads to a number that is very close to a whole number of edits, our cast to int can improperly cause misses.
> ddddd~0.8  will not match "ddddX"
> eeeee~0.8 will not match "eeee" or "eeeeee"
