Add systemd journal support. (#214)
This adds support for reading log entries from the Systemd journal. A new command, called simply 'journal', is added which takes a number of lines as a parameter and optionally which journal (user or system) to read from. Obviously, libsystemd is required to build journal support. Tested on Arch Linux (Systemd v229). Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk>
