First implementation of user defined syntax, many features still missing and probably many bugs

* Implement startToken and endToken in DocumentChildHandler
* Implement pushScopeToken, which pushes tokens for the element that is currently on top of the Scope stack onto the token stack
* Implement rollbackPath() method (was really needed once in the development process, but only used in one place for now)
* Push and pop tokens from stack whenever a new explicit field or command is created/ended. Take advantage of the fact, that the tokens for transparent structures are always included in the token list
* Remember pending close tokens in the HandlerInfo structure in StackImpl
* Implement handleToken() in StackImpl
* Implement readToken() method used by readData() and data() in StackImpl
* Check whether there still is data available in handleData()
* Plus many more changes in the affected files...
