Typically for JavaScript, initialising an object as an array doesn’t
break anything because an array is an object. Anyhow, it should be an
object in this case.
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>>
</$vars>
```
How this Widget differs from the set widget:
* Variables may be created by using the "key=value" notation
that you already know from widgets like action-setfield.
* You cannot specify a fallback ("emptyValue")
* You cannot use a filter to produce a conditional variable assignement
Original discussion that led to the creation of this widget:
https://github.com/Jermolene/TiddlyWiki5/issues/1610
Allow widgets to choose not to propagate actions. This is important for
widgets that themselves trigger actions.
Note that this change will cause problems with any existing
5.1.8-prerelease plugins that call `invokeActions()`.
The tabindex attribute was being set to the string “undefined” if the
attribute was not specified. The fix is to only set the tabindex
attribute if the attribute was specified.
They don’t get automatically decoded when the browser reads the
resulting HTML. So, instead, we’ll solve
1e9e1a1fdc by switching to double quotes
for attribute values.
* Moved “add new plugin” into a modal wizard
* Adopt big friendly buttons
* Add plugin icons and readmes to “add new plugin” modal
* Use tabs for splitting plugins/themes/languages
* Consistent styling between the “add new plugin” modal and the
“installed plugins” control panel tab
* Behind the scenes, moved from addressing the library as
`recipes/defaults/tiddlers/<etc>` to `recipes/library/tiddlers<etc>`
This may cause backwards compatibility problems for people relying on
the block mode parsing, but it’s much better for the rest of us as it
avoids an unsightly paragraph tag
Stop the logger from creating alert tiddlers on the server. They
propagate to the client but are not deletable from the client because
they are in the `$:/temp` namespace.

The previous fix changed the scrolling behaviour such that it only
scrolled to the top of a tiddler if the tiddler was entirely offscreen.
It wasn’t entirely satisfactory because scrolling was prevented even if
only a few pixels of a tiddler are in view. This commit ensures that
the scroll does occur if less than 50 pixels of the target is in view
