Summary: swf8 accessibility - Enable tabbing to items that don't have  
child resources

Bugs Fixed: LPP-7142 - Cannot tab to items that are not clickable

Technical Reviewer: promanik
QA Reviewer: aalappat at laszlosystems.com
Doc Reviewer: (pending)

Details: LzSprite.as - Use a shared __setAAProperty method for  
accessibility properties.  In setResource(), use a 1px by 1px  empty  
resource if accessibility is on to help screen readers see the view.   
Reset the movieclip's __accProps hash in setMovieClip().

LaszloCanvas.lzs - Process accessibility arg and turn on accessibility  
for the root sprite if true.

Tests: See LPP-7142 for a testcase.  Tabbing now works across all 5  
views.  Also, each one is announced by JAWS.  See LPP-7142 for a link  
to the M$ accessibility tools which have a handy tool (inspect32.exe)  
that can validate screen reader properties are being exported.
