Summary: support try/catch/finally and throw statements in SWF7/8
New Features: try/catch/finally supported in SWF7/8.
Bugs Fixed: LPP-1539

Release Notes:
try, catch, finally, throw statements are now supported in
SWF7/8 as well as DHTML
runtimes.
Details:
try/catch/finally are very helpful in creating a reliable software.
It should help in consolidating/maintaining code in the runtime
kernel,
since DHTML already supports try/catch and we won't need to have
alternate implementations of error handling code.
Tests:
created some simple tests using try/catch/finally,
also try/catch (no finally). Had some problems with
my try/finally (no catch) example.
The only way I've found to trigger an exception
in SWF7/8 is to use an explicit throw statement,
since the SWF instruction set seems to continue to operate
with various kinds of errors.
