[fixed] Shared library sonames and symlinks

[mgiuca]

I have been working with Irrlicht SVN head and it seems a number of bad changes have been made since the release of 1.7.2 which break the shared libraries on Linux and other Unix-like platforms. I'm putting them all together into one bug since they are closely related. None of these bugs affect 1.7.2, only the SVN head.

The full bug report with a patch to the Makefile is here:

Thanks for merging, hybrid. One thing: I just realised that I left off the documentation fix out of the patch. It was a minor fix to "changes.txt" which removes the text: "Binary compatibility is only confirmed between minor releases, so the only useful symlink is from libIrrlicht.so.1.8 to libIrrlicht.so.1.8.0; others should rightly fail."
That statement is no longer true, since the Makefile now creates a symlink from libIrrlicht.so to libIrrlicht.so.1.8. Here is the patch against changes.txt:

Ok, I've added this as well.
