Current working copy of the lsces fork of bitweaver

This is a fairly drastic restructuring of bitweaver to make the code base more in sync with PHP8.4 along with Smarty5 and adding namespace to the mix. I am not completely happy with the impact of adding namespace but it is at least working on my own production websites so I am hoping that I can now build on what I have achieved so far and eliminate some of the hacks that were needed to get everything stable on PHP8.4
