[Toolbar] Fixes for IE Favourites 'menu'

[Sylvain Petreolle]

This patch makes IE work beautifully.
Its much better than with the native comctl32.

It also uncovers another misbehaviour in our comctl32.
IE crashes because TOOLTIPS_GetTipText isnt protected against NULL read
attempts.

180         if (HIWORD((UINT)toolPtr->lpszText) == 0) {
Wine-dbg>p toolPtr
0x00000000
Wine-dbg>list -
170         if (oldBkMode != TRANSPARENT)
171             SetBkMode (hdc, oldBkMode);
172     }
173
174
175     static VOID
176     TOOLTIPS_GetTipText (HWND hwnd, TOOLTIPS_INFO *infoPtr, INT
nTool)
177     {
178         TTTOOL_INFO *toolPtr = &infoPtr->tools[nTool];
179
180         if (HIWORD((UINT)toolPtr->lpszText) == 0) {
Wine-dbg>

Quick fix attached.
