* Update README: Names of binaries have changed, CLI interface as well,
add instructions for installing tenders...
* Install an empty log
* Add assertion in albatross_log.service that the log file exists
- console creates the run directories (albatross albatross/fifo albatross/util)
-> log depends on console
- albatross/fifo needs special permission (albatross_daemon creates fifo there, albatross_console needs to read them)
- use /var/lib/albatross/albatross.log for the log file
- only require root in albatross_daemon, use user albatross in albatross_console and albatross_log
- defer albatross_stat for now
