<i18n dev> RFR: JDK-8285932 Implementation of JEP-430 String Templates (Preview) [v15]

[Jim Laskey]

> Enhance the Java programming language with string templates, which are similar to string literals but contain embedded expressions. A string template is interpreted at run time by replacing each expression with the result of evaluating that expression, possibly after further validation and transformation. This is a [preview language feature and API](http://openjdk.java.net/jeps/12).

Jim Laskey has updated the pull request incrementally with one additional commit since the last revision:

  Switch from anonymous classes  to carrier based StringTemplate implementation
