Link checker: user interface and supporting fixes (part 1)

Link checker: user interface and supporting fixes (part 1)

Add open-ils.url_verify service to example OpenSRF configs
ML methods to create sessions and do the searching/bucketing
    We can't use PCRUD to create url_verify.session objects because a) you
    couldn't trust the creator field if we allowed that, and b) the
    container foreign key has a not-null constraint, so you have to create
    that first, and you can't do that with PCRUD.
    I've removed the C, U and D perms for PCRUD for url_verify.session, but
    I left the R in case we wind up using that.
Beginnings for the big session kick-off UI.  Not yet functional.
Get all search results, not just first 10
Check for session ownership and for previous searchitude
Deal with moved publish_fieldmapper() method
    This is a companion commit to
    fac45ab9b1cb8924 / Move Fieldmapper API call to Application.pm
    Without it, Flattener and Action/Trigger stop working with errors like
    this:
    [Mon Aug 20 13:50:18 2012] [error] [client XXX.XXX.XXX.XXX] Exception:
    OpenSRF::EX::ERROR 2012-08-20T13:50:18 main -e:0 System ERROR:

Use a perm that actually exists
More UI work. Saved search selector & search scope OU selector & cosmetics
Fix subtle Perl issue
    Not a syntax error that the compiler will catch, but see
    "perldoc -f do" which will lead you do "perldoc perlsyn"
Buckets and their items aren't designed to be PCRUD accessible,
    so we need a handy view to link URL Verify Sessions to the bib
    contained.  We can leverage this in flattener queries.
Pretty much finished session create UI but for cloning
Permisison fixing
whitespace
Fix previously nonfunctional stored procedure url_verify.extract_urls(INT,INT)
Call URL extraction phase from UI
Fix xpath generation to match what works
Various fixes, largely UI
Refactor create_session as dojo module.
Fix IDL permissions that require jumps
Essentials for URL selecting interface
Verification sorta works
A note about open-ils.url_verify.verify_url for future reference
