In SCI01 and up, each typed word may be interpreted as multiple
class,group pairs. This patch adds support to the vocabulary and
parser. It uses the matcher support added in r52985.
This fixes parser issues in German LSL3, but needs testing.

This is to prepare for multilingual SCI versions. In those a single typed word
may be parsed to multiple class,group pairs, any of which may match
the said specs. The actual parsing is not yet implemented.
svn-id: r52985
We now use a manual parser instead of a bison-generated one, and the
new code to match said trees with parse trees matches sierra's more
closely.
Also change the parse/spec tree nodes to use direct pointers to
their child nodes to make it more convenient to manipulate the trees.
This has a high potential for regressions.
