Complete rewrite of the evaluator to get rid of the code from mark Morley (because of license issues). The new Evaluator does a pre-compile of expressions, and stores them in trees. Therefore it should be reasonable faster... git-svn-id: https://ssl.bulix.org/svn/lcd4linux/trunk@387 3ae390bd-cb1e-0410-b409-cd5a39f66f1f
