Add support for multiple accounts in set account

The set account for control channels is now a comma separeted list of
accounts instead of just one. If the user changes the tag of an accounts
trough `account <id> set tag <new_tag>`, the account set will be updated
to reflect this change for all relevant channels. If an account is
removed trough `account <id> delete` it will be removed from the account
set for all relevant channels.
