Merge pull request #19 from sargon/firewall-block

Extension to block defined IP-spaces (v4 & v6)
config: Add comment
config: New type for defining key-value configuration pairs.
config: Replace code with new helper type.
meta: Add ability to exclude dns zones.

Add the ability to exclude zones from being generated while processing
icvpn-meta data.
meta: Extract common pull/reload flow, use git hook.

Instead of checking for changes, via comparing version hashes, use the
hook mechanic of git.

We still want to be able to trigger the functionality by hand, hence we
encapsulate functionality into seperate function. And made them callable
via parameters. Now we can call for pull or just reload. Which wasn't
possible before.

For further reusability we extract the script flow.
fastd: Use git hook for change detection.

Also apply just emerged flow abstraction and rename autoupdate_fastd_keys into update-fastd-keys.
