Subject: [PATCH] ICU-13413 Java 7 migration in build scripts and eclipse
 project files

- Updated javac/javadoc source and target Java version to 1.7.
- Eclipse projects to use execution environment JavaSE-1.7.
- Replaced java6.bootclasspath with java7.bootclasspath.
- Removed pre-Java 7 conditional build targets.
- Deleted stylesheet for JDK6 build.
