Make array_pair an extra grammar rule, for cleaner grammar and correct $line

Rename tests from Unit_ to PHPParser_Tests_

Allow to pass a string to the constructor of Node_Name

Give all Scalar nodes and the special nodes Name and Variable specialized constructors for easier use

Remove unused files

Don't save whether a string is binary anymore. The binary flag isn't going to be used in the next couple of years, so it doesn't make sense to unnecessarily complicate things.

Don't save quote type for strings anymore (as it is irrelevant for script execution)

Fix analyzer.php

Add NodeTraverser documentation

Update testsuite

Add possibility to delete and merge nodes in traverser

Use classes for visitors

Let the pretty printing methods for statements decide for themselves whether or not they add a semicolon. Only automatically add semicolons for expressions.

Add possibility to pretty print expressions to PrettyPrinter

Further Name node methods

Make the resolve type of a name a normal subnode (type)

Properly handle fully qualified and relative names

If the short alias syntax is used compute the alias instead of setting it to null

Merge preprocessor.php into rebuildParser.php. Don't distribute the temporary preprocessed grammar anymore

Allow use of normal dollar variables in .pre.phpy (by transforming them to #hash variables for kmyacc)

Add checks against use of self / parent class names and static constructors

Add getLast and toString (and __toString) methods to Node_Name

Rename "ns" to "name" in Stmt_UseUse

In rebuildParser.php output stderr too (so there actually is output)

Don't generate y.output file anymore as it really bloats diffs
