Cygwin Terminal icon broken on case-sensitive systems

[Andy Koppe]

I'm afraid there's a problem with the new "Cygwin Terminal" icon
(which I'm sorry not to have spotted when reviewing the change).

Setup.exe creates the mintty shortcuts with '-i /Cygwin-Terminal.ico',
yet the icon file it creates is called 'cygwin-terminal.ico', i.e. all
lowercase. This means that users of systems with case sensitivity
enabled just get to see a dialog box saying "/usr/bin/mintty: could
not load icon from '/Cygwin-Terminal.ico'".

Apparently at least two users have fallen foul of this already:
