Added Fl::first_window(window) to change which window is at the top of

the window list.  This window is used as the "parent" of any modal
windows you create so it is a good idea to be able to change it.
Normally it is whatever window got the last event.

Fixed Fl_Menu::global handler to use first_window so if a modal window
pops up in response it is parented to the window containing the
menubar rather than the current top window.  This was an annoying bug!

Copied fl_line_style() and the line_style demo over from fltk 2.0
because I am tired of mailing this code to people.  Better to advertise this
as "added fl_line_style() function to set line thickness, dash patterns,
and end caps".

Fixed the documentation for these changes.
