feat(modal): rewrite $dialog as $modal

BREAKING CHANGE:
* `$dialog` service was refactored into `$modal`
* `modal` directive was removed - use the `$modal` service instead

Check the documentation for the `$modal` service to migrate from `$dialog`
fix(tabs): evaluate `vertical` on parent scope

Closes #849.
feat(pagination): `total-items` & optional `items-per-page` API

Closes #820.

BREAKING CHANGE: API has undergone some changes in order to be easier to use.
 * `current-page` is replaced from `page`.
 * Number of pages is not defined by `num-pages`, but from `total-items` &
  `items-per-page` instead. If `items-per-page` is missing, default is 10.
 * `num-pages` still exists but is just readonly.

  Before:

  <pagination num-pages="10" ...></pagination>

  After:

  <pagination total-items="100" ...></pagination>

fix(typeahead): highlight return match if no query

This makes the highlighter behave more consistently like other filters.

It also makes it more useful as an empty query doesn't result in an
empty result.
fix(typeahead): keep pop-up on clicking input

Also, keep reference to event listener to unbind when scope is
destroyed. (Memory leak)
