Add tools.jar to compile server classpath.
#SCL-5260 Fixed
The problem was related to running an in-process Java compiler in JDK7 (since Java 7 tools.jar is not included by default).
Don't show messages on compile server startup/shutdown.
Re-enable parallel compilation. Suppress auto-make only when compile server is enabled.
CompileServerLauncher: don't check tools.jar presence.
JavacOutputParsing: process "Note: ..." as warnings.
Add "More info..." link to a message about the new compilation subsystem.
