[lazarus] Patch: redraw and menu fix (win32)

[Micha Nelissen]

Hi,

Applied is a patch with 2 fixes:
1) do not dispatch wm_paint message before handling it. This fixes the empty
form, because the form is painted (by calling defwindowproc) and then
erased, by calling wincontrol.wmpaint, beginpaint, erasebkgnd, etc. Ie. the
order was wrong, we need to get it right. This is the first step.

2) the menu parent of parent patch. If you reference parent of parent menu,
you need to use parent's commands, not own.

Regards,

Micha.
