Expose HTTP::StaticFileHandler

[icepaco]

I would like to use the BakedFile in order to embed a static folder in the crystal exe. This way I can embed multiple clients that would be hosted with the server since their folders would be 'baked in' :)

HTTP::StaticFileHandler works directly with an actual file system, so it cannot see baked files.
My recommendation would be to create a modified version of HTTP::StaticFileHandler which replaces the file system interaction to operate on the baked file system.
