Proper handling of decimals for string() calls.
...
When calling the string() XPath function floats with zero decimals (10.0, 5.0,
etc) should result in a string without any decimals. Ruby converts 10.0 to
"10.0" whereas XPath expects "10".

Revert "Return XPath integers as actual integers."
...
The particular case of string(10) having to return "10" instead of "10.0" will
be handled separately. Returning integers breaks behaviour/expectations
elsewhere.
This reverts commit 431a253000

Return XPath integers as actual integers.
...
This is to ensure that calls such as string(10) return "10" and not "10.0". It
also saves integer -> float conversions when they're not needed.

Better setup for XPath predicates.
...
This allows filtering of nodes by indexes (e.g. using last() or a literal
number) and uses the correct index range (1 to N in XPath). The function
position() is not yet supported as this requires access to the current node,
which isn't passed down the call stack just yet.

Fixed lexing of XML comments.
...
The previous setup would consume too much. For example the following HTML:
<a><!--foo--><b><!--bar--></b></a>
would result in the following T_COMMENT token:
"foo--><b><!--bar"
The new setup requires the marking of a start position. I'm not a huge fan of
this but there doesn't appear to be a way around this.

Failing XPath spec for double slashes.

The lexer doesn't lex things correctly due to "//" and "/" both being separate

".//foo".
