* Rename raft-notary-demo project to notary-demo
* Refactor serialisation filtering to allow BFT SMaRt to work, it no longer relies on the jdk.serialFilter system property
* In NodeBasedTest remove whitespace in node directory names for consistency with cordform and driver
* Raft notary demo now defined in one place that both IntelliJ/driver and gradle/runnodes can run
* New module cordform-common for code common to cordformation and corda
* Add single notary demo
* Use same java.home as caller in terminal window case, previously only headless case did that
* Bump gradlePluginsVersion as I've changed NodeRunner
On Linux:
* Prefer JAVA_HOME over PATH
* Use correct escaping
* Start sh on failure so that terminals don't disappear taking error messages with them
