String changes for evolution-exchange

[Sarfraaz Ahmed <asarfraaz novell com>]

Hi,

There have been quite a lot of string changes in evolution-exchange. 

Most of this has been because of the code migration from evolution-
exchange to evolution-data-server [ under servers/exchange directory ]
and evolution [ under evolution/exchange-operations directory ].

Most of these strings were already translated as part of evolution-
exchange changes, but have now been moved to either of evolution or
evolution-data-server. So, i am not sure if retranslation would be
needed. Most of these strings should only be in evolution, and we are
trying to move the remaining strings from evolution-data-server to
evolution eventually.
