JACE: Finally usable for a change

[BLuRry <brendan.robert@gmail.com>]

(Sorry for the cross-post, I think there's less readers of the
emulator board than the main apple2 one)

Jace (Java Apple Computer Emulator) has finally been poked and prodded
enough to be a usable emulator.  It's not AppleWin, nor will it ever
try to be.  But it is cross-platform friendly and runs well at least
in Linux.  Most likely it runs well from any platform that has Sun
Java 6 or OpenJDK 6 or higher.

What's new:
-Better speed throttling, no more emulation lurches when sound starts/
stops.  Experience is overall much smoother than before.
-Auto-accelerates when disk access is detected, so boot times and
CATALOG are a lot faster.
-Primitive joystick support (uses mouse movement for now, more options
will be forthcoming later such as keyboard mappings)
-Hard drive (HDV/2MG) support (also 800kb floppy images) for reading/
writing
-New configuration interface that allows tweaking various aspects of
the emulator -- still a work in progress but some things work.  (You
have to use it to insert a hard drive image)
-Any card configuration is possible.   7 hard drive controllers?  Why
not.  14 floppy drives?  Go for it.  (why??).  Default configuration
is Slot 2: SSC, Slot 6: Disk ][, Slot 7: Mass storage
-Configuration SAVE will store settings to be automatically loaded on
next startup.  Settings are saved in .jace.conf (delete this to revert
settings to defaults on next start)
-Super Serial Card emulation can optionally strip/add LF characters
for you -- useful for telnet support in some cases, but it's not
complete telnet support like Kegs has.
-Nice shiny startup help screen, with more helpful features to be
added later.
-Aspect ratio correction (Press F8)
-Paste support (shift+insert)
-Experimental console support that redirects character input/output to
stdin/stdout (doesn't work very well though) -- you can enable/disable
it from the config screen.

Download:
http://sourceforge.net/projects/java-ace (download should be 600kb or
so, if it is >700kb then it is likely an older copy)

To start: If JRE is registered with your file manager you might have
the option to start the program directly by right-clicking and telling
it to open with Java.  If that option doesn't present itself, from the
commandline use:

java -jar jace.jar

Thanks to everyone here for all the useful help and code snippets
along the way, not to mention very patient testing and helpful
feedback.  Big thanks to Nick and MDJ for lots of help needed to even
get this behemoth off the ground.  I'll still be adding features
periodically, keep an eye on the sourceforge activity for small
progress updates.
