Support other marco values for matching beyond bool.

Should support evaluating some basic matches

@common:if [condition="user.type" is="premium"]
@common:if [condition="user.type" not="premium"]
@common:if [condition="user.type" some="premium,enterprise"] ?

This may be easier to manage than javascript style === && !==
