Update to 1.50

* Included Linux image works fine on NetBSD/amd64 6.99.23

Changelog:
	New features

	    Addition of ports to Amiga OS 3 and OS 4.

	    Sound emulation.

	   Support for RAM sizes other than 4MB (512KB, 1MB, 2MB,
	   4MB, 8MB, 12MB & 16MB now supported).

	   ARM250 & ARM3 CPU emulation.

	   ArcEm clock set from host's clock, partial RTC support.

	   Extension ROM emulation, allowing support for the
	   following new features when emulation RISC OS:

	   HostFS - A RISC OS filesystem to allow use of a
	   directory on the Host Filing system as a virtual
	   hard drive.

	   Mouse scroll wheel support.

	   Extra video modes, up to 1024x768 in 16 colours and
	   800x600 in 256 colours.

       Bug fixes/Improvements

	   Many performance tweaks and optimisations, resulting in
	   a 5-6 times performance gain on ARM hosts. A 600MHz
	   XScale can now achieve a level of performance roughly
	   equivalent to an 8MHz ARM2. Similar performance gains
	   can be seen on other low-power hosts.

	   Video emulation rewritten to provide accurate redraw
	   and VSync timing, down to the scanline level.

	   Video emulation now supports upscaling and aspect ratio
	   correction for rectangular pixel modes.

	   All hardware clocks/timers (IOC timers, video DMA, audio
	   DMA, etc.) now run in real time, ensuring one second
	   takes one second no matter how fast the host machine
	   is.

	   Source code tidied a bit to remove redundant code,
	   including support for emulation of 32bit processor modes
	   (there are other, much better emulators for that!).

	   Source code converted to use C99 number types to aid
	   portability.

	   Instruction prefetch now correctly emulated - ensures
	   correct operation with self-modifying code and some
	   forms of copy protection.

	   RISC OS version now 32bit compatible, and ARMv7-safe.
	   Also much more useable with modern machines/LCD monitors
	   as it no longer requires the host to be able to support
	   Archimedes screen modes.

	   Windows version updated to build under Visual Studio
	   2010 (including Express edition).

	   Unix/X11 version now supports X servers that don't
	   support XWarpPointer.
