[wp-docs] Special Note About the Delete Plugin and Plugin Uninstall

[Jacob Santos]

There has been some confusion on Trac about the purpose and use case 
about the Delete Plugin and plugin authors wanting to be able to keep 
their settings.

The reason the plugin uninstall is part of the plugin delete is so that 
plugin authors can clean up their settings when the user deletes their 
plugin. I think the confusion lies is when the person realizes that they 
didn't want to remove their plugin and find that all of their settings 
are now gone. This should not be the case and should be assumed that 
when the user deletes the plugin, that they also want to remove any and 
all settings, files, and misc stuff that would be considered garbage 
once the plugin is no more.

I'm not sure where to put this on the Codex, so I'm letting you all here 
know in case there is an inquiry in the future or if someone knows of a 
place it should be. I'm not sure there is actually any page other than 
the Version 2.7 notes on the uninstall. It would be nice if there was.
