* Moving keywords and standard types to separate Ada builtins file

* Adding separate AdaLexer to the list

* Fix #632.

The doc string indicates that the linenos table is wrapped in <div class="highlight">,
but the actual implementation puts the <div> inside the table cell containing the code.
This seems to cause issues as explained in #632, and given it doesn't match the
documentation, this PR restores the original behavior.

* Fix sample code in comment.

* Update CHANGES.

* Refactor the wrapping logic.

Instead of calling _wrap_div() at the end of wrap(), _wrap_div()
is now called after wrap/_wrap_tablinelinenos. This yields the
desired behavior but removes the custom <div> generation code.

Nested type names were being highlighted as if they were function names.

Now a phrase like `Spec.Process.run` is highlighted properly as:
- `Name.Class`
- `Punctuation`
- `Name.Class`
- `Punctuation`
- `Name.Function`

Instead of wrongly highlighted as it was before this commit:
- `Name.Class`
- `Punctuation`
- `Name.Function`
- `Punctuation`
- `Name.Function`
