* ptvcursor_push_subtree(), ptvcursor_pop_subtree() for pushing/popping
subtrees. Multiple levels of subtrees (256 max.), allocation per 8 levels.
* Two new functions creating an item in the tree and pushing a subtree at the
same time. These two functions accept an undefined length
(SUBTREE_UNDEFINED_LENGTH). The length of the item is set at the next pop.
1) ptvcursor_add_with_subtree
2) ptvcursor_add_text_with_subtree
- get rid of potential memory leaks with g_new in ptvcursor_new().
- Documentation of the new ptvcursor functions in README.developer
