Rename existing files, removing 'tut_'; fix links accordingly

Have to replace doc links with Wiki+ links when making our current tutorial Comcode pages wiki-ready.

Developer says:
there is a search feature in php.net website (to search for functions,classes,,constants). It would be great if Composr had that.

Maybe we'll embed a Google site search.

Docs merging from
