Convert lib module to Java (#487)

Browse source 
* lib.FileScannerTest: convert to Java

* lib.Filters: convert to Java

* lib.FiltersTest: convert to Java

* lib.Archive: convert to Java

* lib.LocalFileSystem: convert to Java

* domain.Channel: better channel termination

* domain.Channel: improve assurance that threads die

* Ensure uisink and storage shutdown when exiting program

* domain.HashesTest: clean up

* domain.Channel.run() already shuts down channel when runner finishes

* lib.FileScannerTest: add listener before run

* domain.Channel: add lock around take and only interrupt if waiting

* .run: add intellij test run configurations

* app. update in-code version

* app: chain ui channel construction

* domain.Channel: add tracing option and simplify thread naming

* storage-aws: use default multipartUploadThreshold

* app: force exit once program is completed

* domain.channel: split up and move Channel to its own package

* lib.LocalFileSystemTest: convert to Java

* lib.SequencedAction: convert to Java

* domain.LocalFile: don’t box file length

* lib.FileScannerTest: include hashes

* lib.UnversionedMirrorArchive: convert to Java

* lib: remove scala dependencies
