Project tree does not properly sort alpha when number of parents reaches a certain count(?). I'm assuming this has something to do with wx reallocating for more space and breaking the tree structure.
This is not an issue on my other machine with codeblocks 20.03/wxgtk3.05 handles sorting properly, as well as on windows(20.03,nightly,25.03).
Included checks for directories vs dirs & directories vs files in cbTreeCtrl::OnCompareItems(...).
Removed call to ProjectFindNodeToInsertAfter(...) in ProjectAddTreeNode(...) as sorting will be entirely handled by sorting children, as well as adding item as first child as we don't care about order at this point.
