Update css-filters.json

Using FF nightly, the live examples don't work https://developer.mozilla.org/en-US/docs/Web/CSS/filter
However, gecko only accepts url() property (https://developer.mozilla.org/en-US/docs/Web/CSS/filter#Gecko_notes)
Added bug for all IE versions
Update css-transitions.json
+ Firefox: only CSS filter with `url()`

https://developer.mozilla.org/en-US/docs/Web/CSS/filter#Browser_compatibility
Fx Almost v31+
Fx No

https://github.com/Fyrd/caniuse/pull/609#issuecomment-48017258
revert to Almost; url() is part of spec

I spec for both CSS-HTML & SVG: http://www.w3.org/TR/filter-effects/#abstract
