    Rename InsetMathHull::isTable to allowsTabularFeatures
    
    The old name conflicted with the newly introduced Inset::isTable.
    
    Now the meaning is as follows.
    * Inset::isTable() is true when the inset is composed of lines and columns
    * InsetMathHull::allowsTabularFeatures is true when the current type of 
hull allows for tabular-like functions.
