Possibility to exclude specific files

[ElectroLutz]

I would love to have a config entry (or so) to exclude specific files from the default assets when a route/controller/whatever is matched.

In my use case I have a file that's needed on every page except one (because it there causes an IE8 error). Currently this would result in removing the file from the base file and adding it to every asset (which are pretty much in my project) except the one that must not have it.

I see the biggest problem while the build process, because it has to be aware of the exclusion and must build two (or more) files.

I hope you have an idea and I'm looking forward to see a patch.

Cheers
