Change these to the Github wiki.
Web: change a couple of links from Trac to Github wiki.
text_transform.inc: the [github]wiki:xxx[/github] tag linked
to a non-existent boinc-dev-doc repo.
Link to the Github wiki instead.
Got rid of auth_ops_cmdline() (not needed).
auth_ops() is now called in util_ops.inc;
every script in html/ops/ must include util_ops.inc.
Note: for existing projects, the admin web interface
will now show "access denied".
Projects must think about what access control policy they want,
and specify it in project.inc
