Support lgathered and rgathered math environments

Browse Source 
* src/mathed/InsetMathSplit.C
	(InsetMathSplit::validate): Only require amsmath for AMS stuff

	* src/mathed/MathFactory.C
	(createInsetMath): create InsetMathSplit if the latexkey is "split"

	* src/mathed/MathParser.C
	(Parser::parse1): remove "gathered" and "aligned", since these are
	now handled via lib/symbols
	(Parser::parse1): create InsetMathSplit if the latexkey is "split"

	* lib/symbols: Add aligned, gathered, lgathered and rgathered
