Changelog:

 Major highlights of this release:

 o JIT CPU compiler supported on 64-bit Linux and Mac OS X now!
   (Jens made a miracle)

 o MFPR FPU emulation should be perfect
   (Andreas ironed out few remainings bugs)

 o Ethernet support under Mac OS X should be way better
   (Philipp added support for big packets and multi-packets)

 o ARAnyM (with JIT?) now runs also on ARM platform driven by Linux
   (is Jens planning on making a blazing fast ARAnyM on Android?)

 o new config setting "LoadToFastRAM" to load kernel in FastRAM
   (is Andreas working on fixing Linux-m68k issues in FastRAM?)

 o David Gálvez improved NatFeat USB support (now requires FreeMiNT 1.17+)

 There's also a small set of bugs fixed in this release - mainly in Mac OS X
 thanks to Philipp but also some generic things like GPIP (Patrice).
Updated emulators/aranym to 0.9.16
