1.7.14

• added historyCachePerPartesEnabled indexer tunable to disable history cache generation in chunks
  • use this if you have giant repository (say hundreds thousands of changesets) and care about indexer performance and can assign lots of heap memory to the JVM running the indexer (say tens of gigabytes)
• commands section of the opengrok-mirror configuration is now properly checked
  • also in Docker: failure leads to sync being disabled
• fix e-mail address detection in Go sources
• Subversion no longer required for building OpenGrok
