- fixed wrong XML output if no peers are known in Network.xml
- simplified parsing of table properties in wikiCode and ZTableToken
- reimplemented GC heuristics. They are needed to constantly ensure that an amount of free memory is available which is higher than Java's max. limit for performing a Full GC (please use serverMemory.request(long, boolean) rather than serverMemory.available(long, boolean) to provide data for averaging over the last GCs)
