RELEASE LiveCode 6.6 DP1

[Peter Haworth]

Hi Bjornke,
I just tried a simple assert/assertError.  If the assert fails, the
commands in the assertError message handler are executed then the original
handler still continues to execute, so assert exits the handler to the
assertError message handler , then goes back to the original handler.
