My initial research has shown that a drop-in replacement for XML::Simple is
hard to find.  However, if we could parse the input as YAML instead of XML,
then we could use YAML::Syck to load the file and return the same data
structure.

I've copied the <config> block of koha-conf.xml to koha-conf.yaml, and written
a new subroutine to parse that, then modified C4::Context->new to detect the
file type and use either XML or YAML according to the KOHA_CONF value.

My VERY INITIAL tests indicate 2 orders of magnitude improvement in speed on
that portion of code; from hundreds of milliseconds to 1 or 2.  More research
is needed to confirm these findings, but they're encouraging.
