This done according to the TeXbook. This class replaces the individual isMathXXX() methods. The mathClass() method (currently unused) is provided for the following insets: * InsetMathChar (with a revised list of affected characters) * InsetMathSymbol: the class is given by the `extra' field Operators defined in lib/symbols (e.g. \log) are MC_OP * InsetMathFrac is MC_INNER (except nicefrac and units) * InsetDelimiters is MC_INNER * InsetStackrel is MC_REL * The class of InsetScript is the class of the last element of its nucleus (yes, it is a hack, but doing it right is more work). Remove the explicit spacing that was done in the different insets. The spacing will be reintroduced properly in a forthcoming commit.
