This is now 0.4 time.
Config && dry-run work

- now sports a config class that can do all sort of magic / preparation / legacy handling
- new command line flag -d (--dry) that just tries to load the config and exit (will catch a number of config errors, although not all) - need extra work
- new http / https configuration syntax that allows binding individually on any number of ips / port, with specific certificates
- fixes #4 (but not SNI yet)
- fixes #10
- on the road to fix #122
