CSS watcher

[osfameron]

Run with bin/make_css_watch

This watches the .scss files in web/cobrands/* and runs the appropriate
sass/compass commands (as per bin/make_css) on just those directories
with changed files.

I rebased this on current master, removed trailing spaces, and moved a bracket to a different line to match the coding standard, in order to merge. However, I now realise that this won't work properly if e.g. one of the files in web/cobrands/sass is modified - which should cause all of the compass directories to update as they all include those files.

Note that compass has a built in "watch" facility that also fails to spot changes to included files (sigh, why have it at all then?), so if this could do that that would be an improvement :)

[osfameron]

Hmm, good point.

Simplest thing would be to special case changes in web/cobrands/{sass,default}?

Most general thing would be to do a rough parse (with a CPAN module, or just regexp search for @include) of all the .scss files and do a simple dependency graph. As you say, this is the kind of thing that compass really ought to get right (given it already knows how to parse .sass files..., sigh).

[dracos]

Yeah, just web/cobrands/sass, I think, default is a cobrand like all the others. Don't think it's worth doing anything more.

@dracos ok, pushed version to handle that case.
