Quick and dirty port of DosBox 0.73 for x86 AROS.

Networking is disabled and in general there's some room for improvement,
 but here we have a mostly working version version of the latest DosBox
 for AROS. The most important things to note are that running in 16bit
 color is recommended as its both faster and doesnt cause the gfx corruption
 that 24bit color will once you change to from fullscreen and/or back.
 Also running in 24bit color seems to cause long halts to everything other
 than the game/app running in the DosBox window, mostly when a drawer
window is open (including root dirs) and is overlapping the DosBox window
or vice-versa. This is not unique to DosBox and happens with a lot of AROS
 SDL ports. Unfortunately Im not sure what causes it yet. Apart from this
it works quite well.
