Complete patch to bump dnscrypt-proxy to version 1.33
Minor changes to APKBUILD to build with the new sources & make-depends.
confd / initd changed to include the additional configurations to set the alternative
resolver ip / public keys.
Separate patch created to build dnscrypt's dependency libsodium / libsodium-dev
(as it no longer forms part of dnscrypt's sources).
Post-install script is just status / info using the $STRONG / $RED / $GREEN
system colours.
Added /sbin/setup-dnscrypt for changing the resolver dnscrypt queries &
optionally installing unbound for dns caching. This also uses the system terminal
colours. This no longer makes any changes to init.d, it only updates conf.d
