Fix test failures due to precision differences

Travis 5.2 seems to have changed the float output precision, so a test was
failing. Now the numbers in the expected output are also provided by PHP,
so they should be the same.

Fix two tests which would fail on x64

Make $line argument for Comment optional

Also add setLine() method.

Add line number information to comments

Line numbers are stored in the $line property of the PHPParser_Comment
and PHPParser_Comment_Doc classes and can be retrieved with getLine().

Fix parsing of new expressions in parenthesis

The new dereferencing syntaxes (new Foo)->bar and (new Foo)['bar'] were
causing a shift/reduce conflict with the '(' expr ')' rule. When
(new Foo) was encountered (without dereference operators following) the
parser thus threw a parse error.

The fix simply adds a special '(' new_expr ')' rule to expr. This does not
remove the shift/reduce conflict itself, but makes it irrelevant.

This fixes issue #20.

Improve some formatting

Replace \N with .

Older PCRE versions (coming with PHP 5.2) don't support \N yet.

Fix getAttribute signature in Node interface

This fixes a build failure on PHP 5.2.

Fix comment reformatting on Linux

Remove the use of \R (with BSR_ANYCRLF) at two places, as it was causing
problems there.

Update CHANGELOG

Add more extensive Lexer component docs

Update docs

Insert comments when pretty printing

This changset also adds unit tests for Comments and adds a way to test the
pretty printer.

Fix $node->getDocComment()

getDocComment() now returns the last comment (given that it is a doc
comment). setDocComment() no longer exists, as it doesn't make sense
with the comment

Fix $node->getDocComment()

getDocComment() now returns the last comment (given that it is a doc
comment). setDocComment() no longer exists, as it doesn't make sense
with the comment objects anymore. getAttribute() now returns by reference,
so it also works in reference contexts.

Adjust XML unserializer for new comments attribute

Add test coverage for two things

Collect normal comments too, not only doc comments

Comments and doc comments are now saved in the 'comments' attribute, as an
array. The are instances of PHPParser_Comment[_Doc].

Generalize the attribute generation for nodes

Now two arrays are fetched from the lexer: $startAttributes and
$endAttributes. When constructing the attributes for a node, the

Generalize the attribute generation for nodes

Now two arrays are fetched from the lexer: $startAttributes and
$endAttributes. When constructing the attributes for a node, the
$startAttributes from the first token of the node and the $endAttributes
of the last token of the node are merged.

Now the end line is saved in the endLine attribute.

Add progress indicator for test_old.

I hate waiting for something without seeing at least *some* output.

Fix NameResolver to properly copy attributes

Store line and doc comment as attributes

Adjust test_old to use new Lexer injection method

Start refactoring parser skeleton

The yacc parser skeleton with all those odd $yy short names is quite
non-obvious. This commits starts to refactor it a bit, to use more
obvious name

Now the lexer is injected only once when creating the parser. Instead of

you write:
