Unofficial MorphOS version string patch for IBrowse 2.3.

IBrowse 2.3 falsely claims MorphOS system is using AmigaOS.
(Particularily misleading since MorphOS systems are reported as
running AmigaOS 4.0 (!!)).

This is a crude hack that just replace all "AmigaOS" strings with
"MorphOS", and "3.1", "3.5", "3.9" and "4.0" with "1.1", "1.2",
"1.3" or "1.4". Better solution should be provided by the IBrowse 
authors.

There is no warranty. Use at your own risk.
