too much privacy on get_plink() which is left over from Friendica days
rev update
add base64 converters which aren't universal across browsers
provide zid in js so we can use it from client
When toggling safesearch, go back to the directory page, rather than the z_root by default.
Didn't finish it. Gotta' pee.

some more doco for how to finish it.
More safe search - since the default is one, toggle only works after
an initial xconfig is set - the first one will turn safe search on
(ie, do nothing from a users point of view).  Fix that.
e2ee
