Jenkin windows build now working again!

[Justin Mclean]

Hi,

Gavin McDonald from the builds mailing list helped out and installed Pixel 
Bender on the windows slave for us. :-)

I managed to work out the right way of escape the truly horrible default path 
that  Pixel Bender uses so that Jenkins will set the pixel bender environment 
variable correctly.

For those interested this is the magic combination of slashes: 
PIXELBENDER_HOME=C\:/Program\ Files\ (x86)/Adobe/Adobe Utilities\ -\ CS5/Pixel\ 
Bender\ Toolkit\ 2

(Note the unix style slashes for directory separators and back slashes in front 
of spaces and colons.)

Now Jenkins will continue to make nightly build and build the Apache Flex SDK 
if there's any check in activity in the last hour.

Thanks,
Justin
