[javac] Removed warnings about javac.source/target
[lib] Only lock when using the directory
The locks were as long as the workspace was open. This
made it impossible to use ant/bnd/gradle
[bootstrap] Further bootstrap integration
[project] Added an ide macro that is implemented now for Eclipse
This macro can provide you answers about the settings of the
IDE (these settings must also be able offline). Curtrently
supports ${ice;javac.target} and ${ice;javac.source} (which look in the .settings directory)
[warning] Deprecation warning toURL removed
[repo] Used the new getWorkspace to find the workspace also outside projects
[bnd] Show the defaults command
