Initial commit. Copied all files from the following prototypes from their
individual repositories to subfolders of this new repository as part of a
clean-up:

create_epub		-> prototypes\epub
database		-> prototypes\database
editor			-> prototypes\editor
ep_styles		-> prototypes\collaboration
xslt			-> prototypes\transformation

It was attempted to to include the version history (by following this
guide:
http://www.nomachetejuggling.com/2011/09/12/moving-one-git-repo-into-another-as-subdirectory/),
but due to an error (see question on page linked to), this was not
possible.

The following Scripler repositories will be deleted (agreed upon with the
authors) because they contain no substantial value:

editors
gui
instantsave
scm
