* 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
- Introduced a new switch JOURNALD_AWARE
