go-sqlite3 does not implement them properly (in fact, the proper support
was just removed, wtf, mattn). Additionally, go-sqlite3 does not handle
$name or @name properly despite these being supported by SQLite, only
:name works.
Closes#241.
Now imapsql module does not handle authentication. (it was not doing it so well
anyway)
sql_table module was introduced and used in the default configuration as
a replacement for functionality that was implemented by imapsql before.
Parts of maddyctl code were rewritten to make it work transparently with
any IMAP backend or credentials store.
Closes#212.
