uid and paths separator "~" in place of ":"

need a character to split filenames on in certain circumstances.
there problems with use of a colon in filenames, which is legal on posix
but not on Windows."~" fits the bill better being legal on every
filesystem of interest and is unreserved in rfc 3986, needing no escaping in a url.

The reference abstraction is renamed, its content unchanged. Over
the sample collection two filenames move and nothing else does: the
abstraction and database digests are identical, the archive's
members and their sizes are unchanged, and only the member order
shifts, "~" collating after letters where ":" sorted before them. The
document's epub dc:identifier is a v5 uuid derived from the uid, so it
changes for those filenames.

Every document's uid changes in the search database (spine.search.db).
