Subject: [PATCH] Tree.java: correctly escape & in default Tooltip

This fixes
https://github.com/eclipse-platform/eclipse.platform.ui/issues/1075

When TreeColumn's are too small, a ToolTip is displayed on hover to
reveal the whole Label of an Item (The WIN32-Docs call them 'Inline
ToolTips').
These ToolTips pass through the Composite-ToolTipText-generator which
escapes all & in a Text - allowing to reuse Text from Buttons as
Tooltips. This is a well documented Feature of setToolTipText.
Since TreeItem's Label does not have Mnemonics, we do not assume that
the & needs escaping.

This Commit Escapes all & in default Tooltips that are handled by the
default mechanism.
