Make the following changes to Lander:
- Always include the "View on DocuShare" button for controlled document types (LDM, LSE, LPM, and so on). Implement as a whitelist, and use the ls.st short link form. This makes the --docushare-url command line optional have a good automatic default.
- Do not show the DRAFT notice for builds on master and docushare-vN branch/tag names.
