Default template contains misleading metadata

[benbalter]

The default template contains some misleading metadata:

Specifically, the "template", and author, as well as some properties that aren't necessary:

While it doesn't affect the output, it can be a bit misleading when sending the created document to third-parties.

Glad to submit a pull request, but wanted to check in first before I did, in case it was purposeful.

Please do, I don't think any of that metadata is necessary in there (We are not using it).
Probably Cristina just created an 'empty' document.
I can the that the 'tax guide.dotx' comes from the current project we are using it for :)
