* Reformatted and refactored some files

* Added awareness of systemd-journald
- Added dependency for bash in debian control file, because this implementation uses bash arrays
- Changed in all shell scripts the interpreter to bash
- Replaced "service log2ram stop" with "systemctl stop log2ram"
- Replaced "-a" with "] && ["
- Increased SIZE and LOG_DISK_SIZE to 128M and 256M because journald can use a lot of space

* Add existing conf path.

Fix for #147

- Adds support for missing options in the /etc/log2ram.conf (USE_RSYNC and MAIL)

Update README.md

Restart journald command

Merge pull request #164 from pb66/patch-1

Need to use `sudo apt` if not root user. proceeding 2 lines already incorporate `sudo` commands so for consistency these lines should be `sudo` too.

Update ansible playbook

Use new trusted.gpg.d keyring for apt key, improve idempotency,
only update cache when necessary, only restart service when necessary.

- Move "Is it working?" section to after "Install"
- Adjust "Is it working?" a bit, mention "systemctl status"
- Wording
- Add Troubleshooting section with journal cleanup tips

daily hit in the same time as logrotate.
