Memory Managment

I'm re-doing the memory managment as the current memory managment is only really a temparary store in the parser and more importantly, I noticed a couple on memory leeks in the alpha release. Basically the code is so extensive that it is no long pratical to make sure that every new has a matching delete, hence the new memory module. It should be out in about a week.

The new memory managment uses smart pointers, does reference counting and is used not only in the parser, but within the storage classes, so it should be quite handy.
