2ed6cac7c1 Don't traverse nodes merged by another visitor 
If a NodeVisitor returns an array of nodes to merge these will no longer be traversed by all other visitors. That "feature" turned out to be a real pain in the ass on some occasions ;)

1449cc2092 Disallow array deref using alternative syntax 
f(){0} and a::b(){0} aren't allowed anymore (in compliance with PHP).
$a->b(){0} support stays for now (for technical reason).

db3181aff1 More test coverage and doc string parsing fixes 
The parser didn't account for the additional newline after the content of doc strings, which is left there by the tokenizer for some reason. Additoinally esacape sequences were parsed in nowdoc strings.

Additionally this contains some minor changes to the grammar: Some _list nonterminals were refactored to have the possible single elements in a reparate rule and only assemble those single elements. (This reduces duplication and gives better assignment of line number context.)

c7c94f38f1 Stop using ArrayObject for nodes 
Instead manually implement IteratorAggregate and define the required magic methods. The reasoning behind this is:
a) Extending ArrayObject is always risky, because a lot of magic which is known to be buggy is involved
b) This allows to lateron change the implementation for the nodes altogether, for example it could be changed to using real public fields instead of a $subNodes array.
