Bug Fixes:
* Prevented `lapdog.WorkspaceManager` from re-synchronizing the workspace after executing a job, if the workspace was previously offline
* Fixed an error that was preventing Cromwell from retying queries if a previous query timed out
New Features:
* Lapdog Cloud Endpoints now use the latest cryptograpic key in the project, instead of
hard coding the 1st
* The Cromwell driver now recognizes when Cromwell crashes and adds helpful error messages
* Added a notice on the UI homepage when the local lapdog version is out of date
Other Changes:
* Reorganized `lapdog.cloud` code into a module
