-I'm also attaching another patch which removes unisim/roc dependency

-(it was used just to pulse the areset) and fixes paths for building

-the ghdl examples out of the box. I guess this is the easiest way to

-get zpu running on linux with minimum effort.

-

-You should check if the areset change doesn't break modelsim. It feels

-much simpler this way and seems to work the same, i might be missing

-something.

 	* io.vhd: fix address comparsion and added numerous outputs

 	during simulation to make things a bit easier 

 	* zpu_config.vhd: do not use hardcoded startSp, allows more easily

 	tinkering w/RAM size

 	* Small ZPU now supports interrupts

 	* added simulation example demonstrating interrupts
