added a "kupu_save" log entry on saving.

Thus we - as wiki admins - will be able to:

[1] gather stats on kupu editor usage

[2] proactively go to all kupu-edited pages to check for damage, and get user feedback

The patch just add a line

&TWiki::Store::writeLog( "kupu_save", "$_[2].$_[1]", "" );

to lib/TWiki/Plugins/WysiwygPlugin.pm

While I sympathise with the goal, I don;t want to do this for two reasons:

1. There is no writeLog method in TWiki::Func, so I'd have to call the core directly
2. It's easy for an admin to add this if it's really important to them; otherwise it's just code bloat.

Discarded.
