FisheyeLite should use parseFloat instead of parseInt

[ebsq]

I believe I am using version 1.5 - but the code seems to be the same in 1.7

I had been using FisheyeLite? to fade an image in and back out - taking the css opacity value from 0.3 to 1 and back down to 0.3

This used to (seem to) work - I am unsure of when it stopped working (I don't think the code changed - perhaps a browser change). Anyway, I was able to fix the problem by updating line 112 of FisheyeLite?.js

from

   v = parseInt(cs[p])

to

   v = parseFloat(cs[p])

It seems to me that decimal values are being misread as the code currently stands. This was especially noticeable to me since the opacity can be between 0 and 1, inclusive. I wanted the opacity to revert to 0.3 after the effects, it was going to 0 instead.

Sorry if I'm not adhering to protocols - not much of a bug reporter :(
