Fixed getting symbol from document.

Crashed if symbol was at the beginning of text.
Also removed a lot of writelns.
Tweaked readqualified name.

"Prettier" method to get numbers from mangled names.
(S3std5stdio4File).
Must remember to fix getting the typefunction. Skipping to argument close
letter is simply stupid.  What was I thinking?
Completion window was not closing.

With all the symbol changes the "popup" window for symbol completion no
longer closed properly.
ModuleView element finally works!

No only is it about time but it's pretty cool.
