[Themes] add calc() support to distance in theme format. (#1105) 
* Initial test to allow math in distances.

Support + and -
Needs spaces around + and -.

* [THEME] Fix printing theme with math in distance.

* [Theme] use calc() syntax.

* [Theme] Add * and /  to calc().

* [Theme] Fix the precedense ordering in parsing. Also avoid making copies.

* [Theme] Don't print unneeded ().

* [Theme] Add modulo to calc.
