revert idiomatic handling of namings from 5a93b8f928a2 because in combination with Named_Target.theory_init global names are sometimes created

don't forget to init Interpretation and transfer theorems in the interpretation hook

export theorems

abstract Domainp in relator_domain rules => more natural statement of the rule

more appropriate name (Lifting.invariant -> eq_onp)

left_total and left_unique rules are now transfer rules (cleaner solution, reflexvity_rule attribute not needed anymore)

tuned

more accurate type arguments for intermeadiate typedefs

merged

ignore other_id reports for now (see 8eda56033203): massive amounts of redirections to 'class' etc. makes it difficult to edit main HOL; silently ignore excessive reports -- no ambition to detect that situation accurately;

more standard names;

modernized simproc_setup; modernized theory setup;

modernized theory setup;

added simproc markup, which also indicates legacy simprocs outside the name space;

modernized simproc_setup;

NEWS;

tuned error -- allow user to click on hyperlink to open remote file;

no comment -- File.read_stream already enforces UTF8 (like HTML5) and HTTP servers often produce a wrong charset encoding;

improved support for external URLs, based on standard Java network operations;

basic URL operations (with Isabelle/Scala error handling);

proper Args.name vs. Args.text as documented (in contrast to adhoc union in 75aaee32893d, which had to cope with more limited Args.T);

allow text cartouches in regular outer syntax categories "text" and "altstring";

tuned comments (see Scala version);

dismiss popups more carefully (amending 7e8c11011fdf), notably allow mouse dragging within some tooltip, e.g. for text selection;

clarifed results range;

more explicit message discrimination;

avoid confusion about pointless cursor movement with external links;
