Remove useless condition from Throw printer

Swap argument order for Node_Case

$cond is now the first parameter and is not optional.

Remove redundant check in NameResolver

Simplify resolveOtherName logic

Add NameResolver

The NameResolver visitor tries to resolve all names to fully qualified names. It will resolve all non-dynamic names, apart from unqualified function and constant names. The

Add test coverage for Node_Name

And fix bugs found while doing so.

Fix some readme + doccomment typos

Don't use references in NodeTraverser

Stop using reference magic in the NodeTraverser. Instead use normal return values. Additionally enfore that an array is passed to ->traverse().

Merge Node_Name and Node_Name_Normal

Use seperate Name node classes instead of type subnode

Add shared Node_Const

Node_Const is shared between Node_Stmt_ClassConst and Node_Stmt_Const. Maybe one could generalize it to a Node_NameToValue to share it with Node_Stmt_Declare too.

Add missing doc and pretty print for Stmt_Declare

Make some doc comments more precise

Additionally add two further constructors

Move Node_Expr_FuncCallArg to Node_Arg (just like Node_Param)

Add specialized constructors for statement nodes with only one subnode

Add PHPParser_Node interface

Improve NodeDumper performance and make testAgainstDirectory more friendly

Swap argument order for ArrayItem

Some minor improvements (performance and exception wise) for the node traverser

Fix / improve some method doc docomments / signatures

Iterate replacement nodes using all visitors apart from the one having made the replacement

Properly parse escape sequences:

* Add support for oct and hex escape sequences
* Take used quote type into account when parsing encapsed strings

Instantiate a Node_Name for 'static', too. Fix some doc comments.

Fix NodeTraverser by putting to-be-deleted and to-be-merged nodes into the same queue. Additionally do not further iterate queued nodes.

Move Variable to Expr_Variable, move Stmt_FuncParam to Param (as it is used both in stmts and expr and both in funcs and methods)
