uBee512 v4.7.0

uBee512 v4.7.0 is released. uBee512 is an emulator for the Microbee Z80 Premium/Standard FDD and ROM based microcomputers.

New for this release:
* Added BeeThoven emulation. The Microbee BeeThoven peripheral is based on a General Instruments AY-3-8910 Programmable Sound Generator chip.
* Added BeeTalker emulation. The Microbee BeeTalker peripheral is based on a General Instruments SP0256-AL2 speech synthesiser chip.
* Added --parallel-port option to connect addon parallel port peripherals.
* Added --sdl-putenv option to allow SDL environment variables to be set. This can be used to change the behaviour of SDL. The variables supported depends on the SDL version and the SDL documentation should be consulted.
* Added the current SDL-1.2.14 DLL to the Windows distribution packages.

Changes:
* Improvements to speaker sound synchronising with the Z80 when using the BeeThoven or BeeTalker peripheral.
* Changes to the printer port, this can now be set to peripheral devices. A printer (to file) is now just another peripheral that can be connected.
* OpenGL video support handling has changed on Windows systems when SDL-1.2.14 or later is detected. As SDL has fixed some OpenGL bugs in that release some of the existing work arounds are now bypassed at run time. Older SDL versions should operate as before. Improvements on Windows systems may be noticeable.
* Added some SDL environment variables examples in ubee512rc.sample.
* Added --parallel-port=joystick to games.ini.sample.
* Added the required SP0256 ROM alias entry to roms.alias.sample.
* Changes to the volume coding required the default volume percentage to be increased from 15% to 45% to compensate.
* Build platform for Linux binaries upgraded to Ubuntu 10.04 Lucid Lynx.

Fixed:
* Lock keys up/down bug is now fixed in SDL-1.2.14 when the SDL environment variable SDL_DISABLE_LOCK_KEYS is set to "1". This is done internally by the emulator when SDL-1.2.14 is detected. Games such as Micro Defender should now work.
* SDL-1.2.14 has some issues with false mouse movement events when the mouse cursor is disabled. This has been worked around, this has also fixed some existing issues with the mouse cursor in full screen mode. Full screen mode can now start-up with the mouse cursor disabled.
* On Unix builds the time in milliseconds was not being calculated correctly as a 64 bit value.
* The mouse double click detection had the wrong size timer variable which had the potential to cause problems.
