Title: Fix several bugs relating to ToolStrips with Flow layout

Specifically:
- Do not take into account unavailable ToolStripItems.
- Use preferred size of ToolStripItems instead of current size.
- Take into account the ToolStrip's padding.
- Do not fill the ToolStrip height during layout, which is wrong
for multi-row ToolStrips. This reverts commit f124ea39, which
fixed Novell bug #469196. As an alternative fix for that issue,
set ToolStripSeparator's Dock to Fill in its constructor.
