Build node attributes inside semantic action methods
...
Minor performance improvement for parsing, also allows to access
attributes with higher granulity in the parser, though this is not
currently done.
* #n can now be used to access the stack position of a token. $n
is the same as $this->semStack[#n]. (Post-translate $n will
actually be the stack position.)
* $attributeStack is now $this->startAttributeStack and
$endAttributes is now $this->endAttributes.
* Attributes for a node are now computed inside the individual
reduction methods, instead of being passed as a parameter.
Accessible through the attributes() macro.

The paths are now more generic so it can be run from any directory, not
just grammar/.

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.)

Implement the debug parser by extending the normal parser. That way there is no need to repeat all action codes and lookup tables twice.
