Problems setting title of a newly created tiddler

A post was split to a new topic: Use Unusedtitle and Now-macro to Dynamically Define a Unique Name to use with ActionCreateTiddlerWidget

@stobot I did move the info to its own thread, to be able to focus on 1 topic.

@pmario I hope you have looked at the function based solution by me above. I believe it is much easier to follow, and could be improved even further.
