Fix in codegen for inlined sequence nodes. For inlined sequence nodes, generate nested ifs rather than sequential code which does not work when inlined. The reason is that #codeReturn: in inline generates instvar assignment, not method return, so in sequential code the next child of a sequence will be probed even if previous failed. If that happends, the whole sequence fail and therefore we must generate nested ifs to correctly handle this w.r.t. inlining.

Avoid creation of intermediate collection for mapped action nodes.

Fix in codegen: fixed compilation of unknown node: do not hardcode return variable name ...use `self retvalVar` instead

Renamed #codeStoreValueOf:intoVariable: to #codeAssignParsedValueOf:to: to use same naming as #codeAssign:to:

Fixed codegen for empty (mapped) action block. Although empty blocks are useless in practice, they may occur (and do occur in tests)

Do not create intermediate collection when parsing sequence if not necesary. The collection is not needed when the result of a choice is being used in mapped parser. In that case, store parsed objects in variables and inline action code to use these variables to access parsed objects.

Oops, fixed subproject definition (wrong package names)

Updated .mcz exporting code to include a commit message digest ...instead of just exported revision commit message.

Introduced PPCMappedActionNode for PPMappedActionParser. It's compilation is not yet ideal, bot works for now.

Introduced PPMappedActionParser, a specialized parser for map:ped actions. In order to compile nicer code, compiler has to be able to tell between simple (==>) action parser and mapped (map:) action parser.
