[web] Add source for jquery.qtip.js Downloaded from https://github.com/Craga89/qTip1/raw/master/1.0.0-rc3/jquery.qtip-1.0.0-rc3.js Related to #3851121.

[web] Replace minified copy of jquery.flot.js 0.6 with non-minified version Related to #3851121

[web] Update jquery-treeview to the latest version Files copied from commit 61f230828ace1b54c2cc54bc549ece261b11842e of https://github.com/jzaefferer/jquery-treeview

[web/css] move jquery.treeview.css override to a separate file Patched embedded code copies are a maintenance disaster (even more so than plain embedded code copies). Let's not do that.

[web] Stop patching jquery.treeview.js This logically reverts part of e9b7cd2e9012 "allow treeview to work correctly in a tab #345293". The treeview and ajax code have suffered a number of changes since then, this change doesn't seem to be necessary anymore. It is most likely unneeded since f65208c9dbdc "[javascript] use jQuery.one('ajax-loaded') instead of jQuery.bind() in add_onload to avoid multiple callback executions".

[web] Beautify jquery.treeview.js Fully mechanical, just whitespace changes.

[entities/wfobjs] add missing `DBG_SEC` debugging informations and a new `transition` capability

[warnings] put an end to warnings in the sqlite driver over `str` being sent instead of unicode strings

[web/request] clearly mark user_callback-related methods as deprecated The deprecated decorator not only emits a warning at run-time but above all makes the deprecation immediately apparent in the source. closes #3567793.

[book] document __unique_together__, remove bad RQLUniqueConstraint example RQLUniqueConstraint should be avoided whenever possible. Related to #3753250.

[schema] stop using RQLUniqueConstraint (closes #3753250) The last uses are replaced with unique together constraints.

[dataimport] Have ucsvreader's API match that of csv.reader (closes #3705701) 'separator' and 'quote' are replaced with 'delimiter' and 'quotechar'.

[utils] Add a '_cwtracehtml' GET parameter to trace self._cw.w() calls (closes #4601327) The core of this patch is in UStringIO.write(). When tracing is enabled, write() doesn't just append the 'value' argument to the underlying list. Instead, a stack trace is recorded and a special HTML "source" is formatted. The output with tracing enabled is an HTML page, with the original HTML escaped, and made clickable to show the stack trace when the write() call was done. This allows answering the recurring question: "who wrote this tag here?!"

[datafeed] Add a raise_on_error parameter to DataFeedSource.extid2entity And pass the option from various `process_` methods in existing parsers. This makes debugging in tests easier. Closes #4601191.

[test/view forms] use the official, undeprecated API

[rset] kill the rset._rqlst cache Right now it "works" for the standard, internal uses. However when we will fold ClientConnection and Connection, it will hurt, because suddenly we get more cache hits, and the following situation would become commonplace: * there is an un-annotated _rqlst given by the querier * some view (e.g. facets) requests the .syntax_tree, which takes a copy of _rqlst * the view actually expects the rql syntax tree to be annotated, but it was not, hence we crash. Related to #3837233.
