Fix calls to delete versus delete [].

This patch has no effect, but it's more correct and needed to run the
viewer with libcwd with memory allocation checking.
Make the hash table 64 bit compatible. Probably it would be best to replace the whole hashtable with something more type safe.

glodLoadObject very likely needs a major overhaul aswell to make it work.

Removed compile error fix (a cast) that I had added earlier for one line
that now no longer needs it.
