administration.lua: 1.9 - Added flag antihammer. Groups with
antihammer enabled will not be affected by global bans. However,
users who are hammer'd from an antihammer group will also be
banned locally. Bot will now also attempt to kick via bot API
before using tg. Added autobanning after (default) 3 autokicks.
Threshold onfigurable with antiflood. Autokick counters reset
within twenty-four hours. Merged antisquig action into generic.
There is no automatic migration; simply add the following to
database.administration:
autokick_timer = 0
groups[*].flags[6] = false
groups[*].autoban = 3
groups[*].autokicks = {}
