annotate artifacts/src/main/java/org/dive4elements/river/artifacts/model/sq/Sieve.java @ 8870:c26fb37899ca

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Introduced groups for modules. Modules marked with the same group-id, will be put together in the ui. Also using now the localization info from the server instead of localizing the modules again on the client side.
