Add option to save exported variable list to variable

[StephenGregory]

Sometimes I forget what variables I set in a task and have to refer back to the JavaScript to see what I named them. It'd be convenient if a variable was exporting containing that information.

For example, for a helper that does this:

Tasker.setLocalVariable('foo', [1,2,3]);
Tasker.setLocalVariable('bar', "this is wonderful");

Have it internally set jsdebug to:

JS set the following local variables:
Arrays: foo
Strings: bar

So in the Tasker task:

• JavaScript action
  • calls above helper
• Flash action
  • flashes %jsdebug
