Added CSS/XPath Parser.parse_with_cache
...
This method parses and caches ASTs using Oga::LRU. Currently the default
of 1024 keys is used.
See #71 for more information.

Use describe/it instead of context/example.
...
This keeps things consistent with the general testing guidelines in the Ruby
community. This in turn should hopefully make my life easier as I don't have to
tell people to use this rather odd stlye I was using before.

Properly fixed AST for first-of-type/last-of-type
...
This requires keeping track of the current element being processed. This in turn
allows the usage of count() + preceding-sibling/following-sibling.

Functions can't be used in combination with axes, so I'll just need to fix the
position() function to work properly.

Fixed XPath AST for :last-of-type

This should count following nodes, not merely the position.

Fixed CSS evaluation of :first-of-type
...
The old XPath "position() = 1" would work in Nokogiri due to the way they
retrieve descendants. In Oga however this would simply always return the first
node.
To fix this Oga now counts the amount of preceding siblings that match the same
full name.

Removed support for CSS such as "|X"
...
This expression could be used to get all elements that _don't_ have any
namespace. The problem is that this can't be expressed as just a node test,
instead the resulting XPath would have to look something like the following:
X[local-name() = name()]
However, since the XPath predicates are already created for pseudo classes and
such, also injecting the above into it would be a real big pain. As such I've
decided not to support it.

Use the descendant axis for CSS selectors.
...
Instead of using "descendant-or-self" Oga will use "descendant". This ensures
that expressions such as "foo *" don't return a set also including the "foo"
element.
Nokogiri solves this problem in a somewhat different way by using //foo//* for
the CSS expression "foo *". While this works in Nokogiri the expression
"descendant-or-self::node()" is slow as a snail in Oga (due to its nature of
retrieving _all_ nodes first). By using "descendant" we can work around this
problem.

Drop nth-child support of all negative sequences
...
This removes parsing support for selectors such as :nth-child(-n-6). According
to the CSS spec this isn't valid anyway (confirmed by testing it in Chromium).
As a result there's no point in supporting it in any way.
