Allow cycling between multiple log commands

- Introduced a new optional user config command, allBranchesLogCmds
- When pressing 'a' in the Status view, cycle between non-empty, non-identical log commands
- There will always be at least one command to run, since allBranhesLogCmd has a default
- Update documentation & write an integration test
- Update translation string
