pop-up tool-bar

This code adds a minor mode, `tool-bar-here-mode', which is the same as
`tool-bar-mode', except that it affects only the selected frame.

It also adds a "button" named "Tool Bar" to the far right of the menu-bar
whenever the tool-bar is not visible (both `tool-bar-here-mode' and
`tool-bar-mode' are turned off). You can click the button to pop up the
tool-bar on the selected frame for the execution of a single command
(typically a tool-bar button click). The Tool Bar button is absent whenever
the tool-bar is visible, and vice versa.

The idea is to _conserve frame real estate_ but still have quick access to
the tool-bar: No reason to have a tool-bar on each frame. No reason to have
a tool-bar visible all the time; just pop it up when you need it.

Any interest in adding something like this to Emacs (file tool-bar.el)? It's
not intended to replace `tool-bar-mode'; it's just an alternative for people
who might want to use the tool-bar sometimes but don't want to sacrifice
real estate from every frame all the time.
