new SLB config generation procedure

instead of calling generateConfig for each triplet instance,
generateSLBConfig for triplet list is being called. This increases
performance ~ by 2.

+ generateSLBConfig: function generates config for entire triplet list
~ buildEntityLVSConfig: use generateSLBConfig
+ $parser_class global. Used instead of calling virtual SLBTriplet::createParser

- SLBTriplet::generateConfig
- SLBTriplet::createParser
- SLBTriplet::prepareParser
- SLBTriplet::prepareParserForRS
- MacroParser::pushdefs
- MacroParser::popdefs
bugfix: preg syntax error
