facebook: allow root commands without an account identifier

Currently, all roots commands require an account identifier in order to
operate. However, more times than not, there will only be one Facebook
account per bitlbee user. The plugin should allow for the short handing
of root commands, where the account identifier is negated when there is
only one active Facebook account.

This patch allows for users with only one active Facebook account to
negate the account identifier. The negation of the account identifier
is optional. If there is more than one active Facebook account, the
root commands behave as they currently do, and require an account
identifier.
