Using `$name` and `$value` attributes allows more flexibility in how
parameter names are specified, allowing parameter names that are not
valid attribute names.
It thereby reduces code complexity that would arise when setting
many variables using "<$set>".
```
\define helloworld() Hello world!
<$vars greeting="Hi" me={{!!title}} sentence=<<helloworld>>>
<<greeting>>! I am <<me>> and I say: <<sentence>>
</$vars>
```
How this Widget differs from the set widget:
* Variables may be created by using the "key=value" notation
that you already know from widgets like action-setfield.
* You cannot specify a fallback ("emptyValue")
* You cannot use a filter to produce a conditional variable assignement
Original discussion that led to the creation of this widget:
https://github.com/Jermolene/TiddlyWiki5/issues/1610
Allow widgets to choose not to propagate actions. This is important for
widgets that themselves trigger actions.
Note that this change will cause problems with any existing
5.1.8-prerelease plugins that call `invokeActions()`.
The tabindex attribute was being set to the string “undefined” if the
attribute was not specified. The fix is to only set the tabindex
attribute if the attribute was specified.

@welford my apologies it turns out there are a couple of problems, I’ll
comment more on the pull request
Fixes#1415
The problem was that encodeURI() doesn’t encode slashes, which are not
legal in a data URI, although only Safari was failing. We switch to
encodeURIComponent(), which does encode slashes
fixes#592
Introduces and preserves **_origin** field when using drag-and-drop —
bad idea? discard? different field name?

Preserves compatibility with existing invokeActions call in button widget by creating a separate 'invokeActionCall' function to carry out the recursion. Triggering all descendants permits use of action widgets inside list widgets or macros. Also makes it possible to add triggering capability to select widget.
