Improve the accessibility of the Flash player for screen reader users

Hi Aaron,

I'm very interested in your media player project, and particularly the open-source/customisable flash player.
I enclose a patch to add basic accessibility, using the OpenLaszlo attributes - aaactive, aaname, and focusable - see,
http://openlaszlo.org/lps4.2/docs/developers/program-structure.html#d0e3...

To build, set:

• <accessible>true</accessible> - lps-4.2.0/WEB-INF/frameworks/flex-config.xml - TODO.
• accessible=true in lz.embed.swf() call - media_player.theme.inc - in PATCH.
• <canvas accessible="true"> - media_player.lzx - in PATCH.
• --runtime=swf8

I tested on Windows XP Pro, MSIE 7. To test, try:

• NVDA free screen reader for Windows,
• Microsoft/ MSAA Inspect32.

NOTE: I suffixed the aaname attributes for buttons with "button", as their role is announced as "graphic" - is this an OpenLaszlo bug?
TODO: localization, probably by scripting the "aaname" attributes.

I hope this helps. Many thanks,

Nick
