Feature: Convert::raw2filename

[wernerkrauss]

This might be a handy shortcut for sanitising a filename.

See silverstripe/silverstripe-errorpage#8
See silverstripe/silverstripe-subsites#299

So we are replacing FileNameFilter::create()->filter($f) with Convert::raw2filename($f)?

I'm not sure there's a big incentive for this

Thanks for the suggestion, but I don't think the additional reference is necessary for this functionality.

@dhensby it's a similar shortcut like Convert::raw2url(), which ishandy and easier to find for new developers.

Sorry it looks like there isn't enough core member support for this feature.
