Remove (broken) Travis CI integration; add Prerequisites section

Disable TH for GHC <7.6

When `template-haskell' has been built against `containers' <0.5 (as is the case
with GHC <7.6), building Pontarius XMPP (that requires `containers' >= 0.5) will
force a rebuild of `template-haskell'. This seems to break GHC (and might likely
also break `template-haskell').
Specify Conduit >=1.0.1 dependency

Fixes #36.
Change Read/Show instances, update picklers and change LangTag exports

The reason for removing these instances are the same as in #24.

Affected types are: StanzaID, IQRequestType, MessageType,
PresenceType, StanzaErrorType, StanzaErrorCondition, SaslError,
StreamErrorCondition, Version, and LangTag.

It's quite boilerplate and ugly, but I think that it will do for now.
Replace additional `xpPrim' calls

Moved and started using `xpSaslError'.
Added `xpShow' and `xpPriority'.
Change LangTag Show/Read instances, add parseLangTag, fix __GLASGOW...
Utilities.hs: Implemented `IO [Int]' function for reconnection waiting
IQ.hs: Set default time-out value to 30 instead of 3
add waitForStream
