fix #725 Improving test stability

test.aria.touch.widgets.dialog.events.DialogAnimationsTestCase and
test.aria.widgets.container.tooltip.TooltipTestCase were randomly
failing because of timeouts (which were sometimes too small).
This commit replaces the timeouts with calls to waitFor.

Also, renames some tests which had classpath parts starting from
uppercase.

refactor Remove dead code

Remove variables that are created but never used (in some cases, remove
the variable entirely; in some case, just call the method without storing
the result).

Add JSHint build-time check (for `src` files only) for declared but unused vars.

Also, fixes a minor issue that landed in
https://github.com/ariatemplates/ariatemplates/commit/107507a30d0407e46bcbf6dea3cf31ee28c43928#commitcomment-4166998

refactor some positioning/viewport calculations

1) don't recalculate the viewport size in `onViewportResized` in Dialog,
take it from event data
2) round to full pixels in `utils.Dom.calculatePosition`
(`getBoundingClientRect` returns floats)
