[Trac time 20070318 195107Z] 785d0b2aea8b27a7757015ecf61758e702d12435 Fixed #32:
added code folding in preparation for adding Stani's fold explorer
code folding is turned on for all subclasses of fundamental so that the fold intention can be used whether or not folding markers are actually displayed
added new override in STCInterface
made hexedit's HugeTableGrid conform to the STCInterface
[Trac time 20070102 203720Z] Get code folding to work at some point.
