Applied patch [ 592363 ] Owner Draw Round 2 fixes

This patch fixes the following items in the owner draw
code:

* When an item is disabled, yet highlighted, the code
will now retrieve the user's system settings for
greyed-out text and use that color. Previously, the
code had continued to print the disabled text with an
embossed effect, which looked bad when the item was
highlighted.

* Menu formatting, such as hot-key underlining
(example, "&Open"), has been fixed.

* Measurements and alignments with
accelerators/hot-keys has been fixed.
