Support escaping dots in CSS identifiers
...
Escaping hash characters and whitespace is _not_ supported as neither
are valid element/attribute names (e.g. <foo#bar /> is invalid
XML/HTML).
Escaping single/double quotes also won't be supported for the time
being. It's quite a pain to get this to work right in not just CSS but
also XPath and XML/HTML, for very little gain. Should there be enough
users with an actual use case (other than "But the spec says ...!") I'll
look into this again.
Fixes #124

Basic support for the CSS :not pseudo class
...
This does _not_ support element states such as DISABLED, nor does it
support the special handling of namespaces (e.g. *|*:not(*)). Instead
this selector basically acts as a negation, some examples:
:not(foo) # All but any "foo" nodes
:not(#foo) # Skips nodes with id="foo"
:not(.foo) # Skips nodes with a class "foo"
Fixes #125

Case insensitive matching of nodes

Removed compiler arity spec

This spec isn't very useful and breaks on 1.9 due to it apparently
handling arity values differently.

Fixed ancestor-or-self relative to attributes

Replace (path) nodes with nested nodes
...
This changes the XPath AST so that every segment in a path (e.g.
foo/bar) is parsed as a child node of the node that precedes it. For
example, take the following expression:
foo/bar
This used to be parsed into the following AST:
(path
(axis "child" (test nil "foo"))
(axis "child" (test nil "bar")))
This is now parsed into the following AST:
(axis "child"
(test nil "foo")
(axis "child"
(test nil "bar")))
This new AST is much easier to deal with in the XPath::Compiler class,
especially when trying to ensure that each segment operates on the
correct input.
This commit also fixes parsing of type tests with predicates, such as:
comment()[10]
This used to throw a parser error.

Fixed spec for sum() in a predicate

The return value of sum() should be used as a NodeSet index, not merely
just a truthy value.

Corrected the last() compiler spec
...
This spec didn't match the correct nodes due to `1 < last()` always
evaluating to true in this particular case.

large amount of places.
