CLI variables (#2263)
* Add meta-commands \set and \unset (for variables)

* WIP: first pass at variable replacement

* Use a mapReplacer instead of having Command implement replacer

* remove circular reference with variables

* remove the `replacer` interface; just have it be a struct

* use a lexer for variable replacement
