Added checks for `--delta` and `--force` restore options to ensure that the destination is a valid $PGDATA directory. pgBackRest will check for the presence of `PG_VERSION` or `backup.manifest` (left over from an aborted restore). If neither is found then `--delta` and `--force` will be disabled but the restore will proceed unless there are files in the $PGDATA directory (or any tablespace directories) in which case the operation will be aborted.
When backing up and restoring tablespaces pgBackRest only operates on the subdirectory created for the version of PostgreSQL being run against. Since multiple versions can live in a tablespace (especially during a binary upgrade) this prevents too many files from being copied during a backup and other versions possibly being wiped out during a `--delta` restore. This only applies to PostgreSQL >= 9.0 -- before that only one PostgreSQL version could use a tablespace.
Fixed an issue where document generation failed because some OSs are not tolerant of having multiple installed versions of PostgreSQL. A separate VM is now created for each version. Also added a sleep after database starts during document generation to ensure the database is running before the next command runs.

* Fixed an issue where longer-running backups/restores would timeout when remote and threaded. Keepalives are now used to make sure the remote for the main process does not timeout while the thread remotes do all the work. The error message for timeouts was also improved to make debugging easier.
* Allow restores to be performed on a read-only repository by using --no-lock and --log-level-file=off. The --no-lock option can only be used with restores.
* Minor styling changes, clarifications and rewording in the user guide.
* The dev branch has been renamed to master and for the time being the master branch has renamed to release, though it will probably be removed at some point -- thus ends the gitflow experiment for pgBackRest. It is recommended that any forks get re-forked and clones get re-cloned.
Keepalives are now used to make sure the remote for the main process does not timeout while the thread remotes do all the work. The error messages for timeouts was also improved to make debugging easier.
* Added documentation in the user guide for delta restores, expiration, dedicated backup hosts, starting and stopping pgBackRest, and replication.
* Fixed an issue where the start/stop commands required the --config option.
* Fixed an issue where log files were being overwritten instead of appended.
* Fixed an issue where backup-user was not optional.
* Symlinks are no longer created in backup directories in the repository. These symlinks could point virtually anywhere and potentially be dangerous. Symlinks are still recreated during a restore.
* Added better messaging for backup expiration. Full and differential backup expirations are logged on a single line along with a list of all dependent backups expired.
* Archive retention is automatically set to full backup retention if not explicitly configured.
* Better messaging for expiration.
* Fixed already stopped message.
* retention-archive and retention-archive-type now use retention-full and 'full' when not specified.
* Fixed issue where backup-user was required (should default to backrest).
* ExecuteTest now supports retries.
* Fixed issue where log test was not comparing test logs.
* Fixed issue where test logs would not match for ssh connection errors
* Added a new user guide that covers pgBackRest basics and some advanced topics including PITR. Much more to come, but it's a start.
* The website, markdown, and command-line help are now all generated from the same XML source.
* The backup_label.old and recovery.done files are now excluded from backups.
