Subject: [PATCH] Added a script to facilitate setting the proxy host and port and no proxy hosts, and then it concatenates all the java system properties for setting the java proxy configurations and puts the resulting string in an environment variable JAVA_PROXY_CONFIG, modified the scirpts gitblit, gitblit-ubuntu, and gitblit-centos to source the java-proxy-config.sh script and then include the resulting java proxy configuration in the java command
