Grunt cssmin task is removing the pixel fallbacks for rem units

[willmcl]

We need to remove the mixin and just run grunt-pixrem after minification as there is no option in the cssmin task to avoid this. see here

Is this completed?

This is not completed. The pixrem task was not added to the "grunt watch" task so while it seemed to be working when you run grunt, if you used the "grunt watch" task then it cleared the pixel fallbacks out again.

We need to be more careful in methodically performing and then checking the tasks before committing them. Especially as we now have so many project based on this and the updating is a bit difficult.

The commenting in the grunt file needs to be updated to include a description of the pixrem task. There are 3 steps described in lines 120 to 124. A fourth step needs to be added there and then where we declare the pixrem task so the file reads as one story.
