[Typo3-dev] Make configuration simple

Just a quick one - it won't always be more overhead.

For a config situation like

my.config.does.something.like = this

(or in XML:
<my>
   <config>
      <does>
        <something>
          <like>this...
   ...
</my>
)

Now, a common thing in PHP arrays is to do a 
foreach / while / etc. Using xpath all the 
foreach-ing is done at the (compiled and faster) C 
/ c++ level.

I don't think XML will produce a huge overhead I 
quite a lot of cases.
