SAMBA_VOLUME_CONFIG_ should support colons

[Tydus]

Thanks for the great work! I especially like the idea of storing users' (hashed) passwords directly into the compose.yaml.

Currently, the space character in the global config key is specially handled, but sometimes we need colons(:) in the key as well.

FYI: fruit:nfs_aces needs to be in the section [global] in order to work.

Or, we can just support putting custom global config into one key, just like in SAMBA_VOLUME_CONFIG_.

thanks! I'll take a look! maybe I use some special escape sequence like _COLON_ -> I already to something similar for spaces

[Tydus]

Wow that's fast!

Yeah, definitely _COLON_ will do the trick. Waiting for your good news!
