VIVO-2 Modify the build so installers can create a container-neutral VIVO.

Split deploy.properties into build.properties and runtime.properties, with runtime.properties going into the Vitro home directory. Modify ConfigurationProperties to locate the Vitro home directory, either by System property or JNDI Environment variable, or from build.properties, and to read from both build.properties and runtime.properties. Revise the install and upgrade documents for VIVO and Vitro. Change comments and error messages that referred to deploy.properties by name. Change vitro.home.directory to vitro.home
