I should be able to easily create a complex link in QL

QL
Summary: Put the underscore operator from QText into QL.
Allow a full expression in the middle, to easily create complex displays.
Use case: a quick Querki version of the Tech Breakfast app (on my phone), with cards for presenters -- this might make a fine demo example to build on the fly. From a Session, the display of Presenters would ideally be something like:
Presenters -> ___card(""**[[Name]]**

[[Blurb]]"")__
That is, it shows the name and blurb for the presenter, wrapped in a "card", and wraps all of that in a link. By having the underscore operator in QL, we eliminate a bunch of boilerplate.
This is probably pretty easy to implement, but not terribly critical.
