Lex XPath operators using individual tokens.

T_EQ and T_LT.

Upgrade to RSpec 3.0.
...
For this I've enabled both the old expectation and stubbing/mocking syntax. The
old syntax is much more compact and to me reads nicer. For example, consider
the following:
lex('<foo></foo>').should == [...]
To me this reads much nicer than this:
expect(lex('<foo></foo>')).to eq([...])

not ideal but it will do for now.

Support for IO inputs in the lexer.
...
Using IO/StringIO objects one can parse large XML files without first having to
read the entire file into memory. This can potentially save a lot of memory at
the cost of a slightly slower runtime.
For IO like instances the lexer will consume the input line by line. If a
String is given it's consumed as a whole instead. A small side effect of
reading the input line by line is that text such as "foo\nbar" will be lexed as
two tokens instead of one.
Fixes #19 .

Use a method for getting input in the XML lexer.
...
Instead of directly accessing the `data` instance variable the C/Java code now
uses the method `read_data`. This is part of one of the various steps required
to allow Oga to read data from IO like instances. It also means I can freely
change the name of the instance variable without also having to change the
C/Java code.

Replaced fcall/fret with fnext in the XML lexer.

With the rules being cleaned up/moved around a bit we can drop the use of
fcall/fret. This saves the need of having to maintain a stack (position).

Moved various rules around for the XML lexer.

This moves the element related rules to the element_head machine (where they
belong). This in turn makes it possible to lex ">" as a text node, previously
this was impossible.
