Working on SpShDB... Errors and New Functions

Errors:

* We put 3 regular tags and a -clear tag in the "TAG this" box; it worked right, but left the last two tags without their 'x'

* When saving this event, pressing save seemed to cause the tags to clear. This shouldn't happen.

* When creating a new .dxt file by creating a blank document, it spits up -- the "automated" code assumes that you have an existing document. Change the error into mellowly creating a blank, or create a special function for this.
