Jonathan Gordon 2d3c43dffe skin_engine: rework the parser to be closer to the langauge grammar.
The parser was unconditionally scanning things which it thought
were conditional/enum lists (or tag arg lists) when they couldn't
possibly be (i.e < inside a param which should be valid).

This change fixes it (i.e %?and(%if(%pv, <, -50), %if(%mp, >i, 1))
is perfectly valid now.

This *may* break your exsiting skins if you were using %if with < or >
