Non-static local arrays can't be initialized.

[pzembrod]

Currently the words >inittype and (init$ in parser.fth:800-810 encode a rule that forbids array initializers for local non-static arrays. Reason for my decision for this way back was probably this: To implement array initializers for stack local variables would require a memcopy operation whereas static arrays can be initialized in the global initial static var initialization; I probably wanted to avoid the need for the memcopy operation. To be decided how this should be handled going forward, i.e. whether initializers of stack local arrays should be supported.
