Several changes:

 - http connector: dynamic casts -> (safe) static casts
   (improves performance in TechEmpower benchmarks a little bit)
 - Added TechEmpower benchmarks to examples directory
 - WStandardItemModel: use the correct parent for a move-event
 - Fixing issue #5699
   This is actually a workaround for the root cause: clickable widgets are
   rendered as buttons in plain HTML, so a clickable widget inside of a
   clickable widget becomes a button in a button. These are placed next to
   eachother in the DOM instead of one inside the other, and this situation
   is not rectified when JavaScript becomes enabled.
 - Use application's JavaScript class instead of "Wt" in a few places
 - Fixed grammar mistake in widgetgallery
 - Fixed issue #5677
 - Issue #5698: output doubles with round_js_str in WSlider

+TechEmpower frameworks benchmark implementation
+-----------------------------------------------
+
+This example implements the TechEmpower framework benchmark tests for Wt.
+
+How to run
+----------
+
+See the README in the parent directory.
+
+Additional arguments to fit the benchmark requirements:
+
+- `-c wt_config.xml`: config that disables logging
+- `--accesslog=-`: disables access log
+- `--no-compression`: disables zlib compression
+
+What it illustrates
+-------------------
+
+How to implement a simple RESTful service in Wt using custom WResources.
