[WIP] add features from #2163

[devsnek]

add features from issue #2163

closes #2163

• add append option {{content words="20" append="..."}}
• [WIP] change the way append is passed to the helper [Feature] Have an option 'append' to the content helper #2163 {{#content words="20"}}APPENDTHIS{{/content}}

@ErisDS I think that this helper should stay simple and not have all that stuff that #5060 suggests. That way, themers have an option depending on what they want to do. Also, I think that append is a feature, not a silly fix to another problem. I think that the option to make a sentence trail off with a '...' instead of rounding to the nearest sentence is a nice look, and I'm sure other people do as well.

@GusCaplan This needs tests as well.

@acburdine @ErisDS I have written helpers before, and usually you can get the content wrapped in a helper with self, but ghost passes the values differently. What is the ghost way?
