(WIP) Feature/13954 add edit quote comments in wp overview

* The comment edit box and button/cancel link need to be styled
* After the comment has been updated we will have to refresh the work package so that the updated comment appears in the lists. I'm waiting on Till wathers branch so that we can use the same mechanism for this.
I introduced this when the API wasn't returning the updated activity. So, now, we can remove this, I think.
