control panel are all implemented as bx_list_c, and look much like they did before. - removed many hardcoded UI functions from control.cc, since the much more general "text_ask" methods have replaced them. - add range checking on integer parameter values. This exposed several cases where my initial value for an integer parameter was not in range. - cleaned up behavior of get/set methods. The get/set methods allow the handler to override the value that is returned/set, or perform side effects. - the title parameter of a bx_list_c now defaults to the name. - now bx_param_c fields that used to be private are protected instead - removed references to bx_any - moved definition of set_handler from siminterface.h to siminterface.cc. I was considering with doing a "set" of the old value when the handler is first installed, but that remains commented out. - BX_BOOT_DISKA and BX_BOOT_DISKC are now 0,1 so that they can correspond with the values of a bx_param_enum_c. For a while they were 0x00 and 0x80 corresponding to the numbering convention of the bios, but it didn't really matter.
