Sharedir for Module::Build

Hi!

So, to put my SDL-base Spaceinvaders game [0] on CPAN I need to install some 
stuff (images) alongside my dist. Previously I used several different 
homegrown techniques for this, which work. But I'd rather use the sort 
of common File::ShareDir instead of rolling my own. Unfortunatly, 
Module::Build does not support actually installing stuff that 
File::ShareDir can later find out of the box. 

I could now (again) fuzz around add_build_element, install_path etc, but 
I'd rather put all of this into a reusable module, i.e. something like 
File::Share::Install or Module::Install::Share, only for Module::Build.

First question: Does this exist already? Or is there some easy way using 
Module::Build to say "take all the stuff in this dir and install it to 
where File::ShareDir would look for it"?

Second question: Instead of writing a subclass of Module::Build and put 
that on CPAN I'd rather implement this as a mixin (i.e. a distribution 
that exports some methods that then can be used by a standard 
Module::Build instance). What do you think about that?

For the API, I'd like to have something like

   $builder->install_share(@list_of_dirs);

This would go through all the dirs, add the files in these dirs to the 
configuration ('share_files'), add a correct install_path, call 
add_build_elements, maybe add those files to no_index, ..

Any more feedback/ideas?
