[Seaside] Combine several FileLibraries into a single one

[Esteban A. Maringolo]

Did anybody create an utility that enables the merge the contents of
several files in FileLibraries into a few methods into another library?

I mean, for deployment in production I don't want to deploy to disk the
contents of the files to be served statically, but I want to keep them
within the image, but combining them into a single file (or a few) to
avoid having multiple network requests, and cache the contents only once.

So if I have
FileLibraryA>>mylibraryaJs
FileLibraryB>>mylibrarybJs
FileLibraryC>>mylibrarydJs

etc...

And I'd like to have:
CombinedFileLibrary>>librariesJs

CombinedFileLibrary could be a meta-meta library, where #librariesJs has
the file description, but the contents is built dinamically somehow.

Does it exist, or should I build it? :)
