'+' in directory name causes errors when using as path-prefix

[nlmarco]

The '+' (plus) is replaced by a ' ' (space) when having a client-repository connected at a sub-directory to the server-repository and when this sub-directory contained a '+'.

[nlmarco]

It turned out that java.io.File.toURI() caused the '+' to stay unchanged (instead of converting it to '%20' and a later java.net.URLDecoder.decode(...) invocation replaced the '+' then to a ' '.

I fixed the problem by introducing co.codewizards.cloudstore.core.util.UrlEncoder and co.codewizards.cloudstore.core.util.UrlDecoder and using these instead everywhere. They are mostly copies of the java.net-classes.

Note, that this problem affected only scenarios having the '+' in the path-prefix, because all relevant other codes were using org.glassfish.jersey.uri.UriComponent.encode(string, UriComponent.Type.PATH_SEGMENT) which does not cause any problem with '+', either.
