Subject: Java 9 optimization by caching rt.jar (#239)

* Upgraded Ammonite to 1.0.5-7-f032887 that includes a Java 9 performance optimization for mill's client-server mode (lihaoyi/Ammonite#773).

* Java 9 optimization for interactive mode by caching rt.jar.

* Refactored based on @lihaoyi's comments on #239.

* Removed client side rt.jar caching.

* Propagatio of home path from Cli.

* Propagation, propagation, propagation!
