Framework blockers

[Antranig Basman]

I have attached fixes to the two issues which we considered might be 
framework blockers during IRC yesterday - JURA has raised the following 
as a fault in the primeCacheFromResources function

http://issues.fluidproject.org/browse/FLUID-3899

and the following reopens the original "deadMansBlur" issue which was 
found to have a faulty implementation on IE8 (and on investigation, in 
real fact on every browser)

http://issues.fluidproject.org/browse/FLUID-3487

Please review these patches and commit them if it is deemed they really 
are blockers for this release.

Cheers,
Antranig.
