Fix: WYSIWYG now returns valid HTML in tables

The WYSIWYG by default creates invalid HTML5. Creating a table and running it through W3C validator returns the following error: The border attribute on the table element is obsolete. Use CSS instead.
Update dataobject.md

There's no way to make things like [api:DataObject->beforeUpdateCMSFields()] work, is there?

Update templates.md

Changed Fragment links to Anchor links, however it's is slighty confusing what the right name for the thing is.
According to w3.org: "Some URIs refer to a location within a resource. This kind of URI ends with "#" followed by an anchor identifier (called the fragment identifier)." - http://www.w3.org/TR/html401/intro/intro.html#fragment-uri

After doing some research in the most common used name for the #some-link identifier I came to the conclusion that most of the time (about 70% on StackOverflow/BlogArticles/Interwebz) Anchor-link was the term used to describe the identifier. Imho, Anchor is the prefered term for the identifier.

Is it acceptable to change fragment to anchor, since it seems more used?
