Comp('data-foo-bar' => 12, 'data-baz-woggle' => "strng") can be shortened

[catmando]

the following works with data and aria tags:

Comp('data-foo-bar' => 12, 'data-baz-woggle' => "strng")
can be written as
Comp(data: {foo_bar: 12, baz_woggle: "strng")

In otherwords data attributes can be provided as a hash, and snake case will be dasherized automatically.

Also works with aria attributes
