Enable $wgImportSources for Hebrew Wikivoyage

This patch enables $wgImportSources for the
Hebrew Wikivoyage project per request.

Although the community did not specify what
wikis they'd like to import from, I'm adding
all the remaining Hebrew projects as this
seems to be their custom, and Commons too.

See bug for URL with on-wiki consensus.
