Mikubot-2/otouto/bindings.lua
topkecleon acc7046d64 administration 1.13.1
Added optional target for kick/ban logs. Added flag 7 to use default log
 per group. This way, a realm can have a public kick/ban log but governors
 are able to opt out. Added flag 8, antilink. Kicks for Telegram join links
 which do not refer to groups within the realm. Added flag 9, modrights, to
 give moderators access to changing the group photo, title, link, and motd
 (config option is deprecated. RIP). /unban will reset the target's autokick
 counter. Added configuration for default flag settings.

Revision to bindings.lua.
BASE_URL has been moved to bindings. There is no real reason for it to remain
in instance. Token is passed to bindings.init at load. All plugins have been
updated accordingly.
