This changes the return type of at least the following functions from IO Bool to IO (Either XmppFailure ())
* sendIQ
* sendIQ'
* answerIQ
* sendMessage
* sendPresence
rename reconnect to reconnectNow
* reconnect immediately
* function returns failure mode on error
add reconnect function
* retries when reconnect failes
* waits exponentially increasing amount of seconds between attemps
* returns last encountered error when all attempts fail
The way I understand it, the `Show' and `Read' instances are for `String' representations that can be Haskell code. A proper `Show' instance of `Jid' would produce something like `Jid (Just "test") "example.com" Nothing'. A proper `Read' instance of `Jid' would parse something like that `String' value, and would stop parsing when completed.
This patch automatically derives the `Show' instance from `Jid'. It also uses the previous `Show' instance to create a pretty printer, `jidToText'. It also provides a (trivial) `jidToTexts'. As an automatically derived `Read' instance could be used to create invalid `Jid' values and affect the correctness of applications using Pontarius XMPP, such a derivation has not been included. This required some changes in the `Jid' marshalling code, which assumed a `Read' instance.
Since we provide `jidFromText', I'm assuming that no-one needs a `Read' instance of `Jid'.

`openStream' and `session' now takes a `HostName'. If the hostname is
an IP adress, we connect to it using the default XMPP port. If it's a
hostname, we perform the SRV lookup (or fallback on A/AAAA lookups and
the default XMPP port).
This patch allows for the use of a socket and socket address pair in
the settings, giving advanced users additionally flexibility. This
field can also be used by users that want to use a non-standard port
in combination with a) a misconfigured XMPP domain name (one without
SRV records), or b) connection by IP.
The "manual" A(AAA) lookups have been kept in order to allow the
Pontarius XMPP client to attempt to connect to multiple IP addresses.
