New for this release:
* The new sound driver is now the default with the older code having been
removed altogether. The new code produces excellent sound quality and has
less drop outs.
* Added an audio DAC parallel port device argument of ´dac´ to the
--parallel-port option to select the new 8 bit DAC emulation.
* Added EMUKEY+PAGEDOWN hot key to emulate a Microbee ´power cycle´. This
action has also been added to the OSD menu.
* Added --powercyc option to perform a ´power cycle´.
* Added joystick Hat events to generate pseudo button numbers.
* Added --js-hat and --js-hatb options to set joystick hat parameters.
* Added --js-kkb option to make defining mapped joystick keys easier.
* Added --js-shift option to set the new joystick SHIFT button feature.
* Added joystick SHIFT button functionality that effectively doubles the
number of button actions to 255-511.
* Added ´hd-teac´ and ´hd-mscribe´ hard disk formats to the
´libdskrc.sample´ file.
* Added Swedish PC85 ROM set (PC85S) aliases to ´roms.alias.sample´

* Joystick shifted button numbers 256-511 can now be specified.

JS Shift+C : Pause emulator on/off (5).
JS Shift+Up : increases sound volume.
JS Shift+Down : decreases sound volume.

* The BeeThoven device no longer requires an ´OUT 1,3´ before using it.
* Improvements in speed made to CRTC functions.
* Major changes to the ´games.ini.sample´ and ´ubee512rc.sample´ scripts to
make setting up the joystick easier and more flexible. Emulator commands
now make use of a Joystick shift button.
* Changes made to the ´ubee512rc.sample´ file.

Fixed:
* Changes made to --varuset option so that ´varname´, ´varname=´ and
´varname=value´ all work.
* Fixed --setvar option when attempting to set a variable that had no ´=´
character. The variable was being set but could not be located without it
so now one is appended if missing. ´--setvar myvar´ will get set and
found.
* Changes made to --setvar option to first check for an existing variable by
the same name and removing it before setting the new variable.
* The --js-axis option was doing nothing and has been fixed.
* Fixed hard disk image type ´.hd0´ to have 306 cylinders, not 305.
