Aqsis 0.9.3 released

Source and Win32 packages, RPM's to follow.

This is mainly a bug fix release, lots of bugs eliminated. Some optimisations and changes in functionality, see the changelog for details.

This should be, fingers crossed, the last release before 1.0. I hope to clean up the last of the bugs before 1.0, but if time proves to be against us, it may get released with a couple of known minor bugs.
