Fixes - mostly dealing with the "Assert" fn

[mbaas2]

[540] look for "verbose" in current ns and parent [544] avoid INDEX ERROR (could happen when ⎕LC[2]=1 [770] do not copy "verbose" into ns (see 544) [1805] set type←3 if it was not explicitely set (=0)

We should probably look at how "verbose" might not wind up in the namespace that Assert uses. Is there a path through the XTest code that allows this?
