GO Contact Sync Mod Code

IMPROVEMENT:
- addes EnableLaunchApplication to start GOContactSyncMod after installation
as PostBuildEvent

FIX: i+1 instead of i in progress notification

Improvement: added progress notifications (which contact is currently syncing or matching)

CHANGE:

- uncomment AssemblyFileVersion-property to get the same version as AssemblyVersion
- if we deploy a new setup we have to change the version number to that version to
automatically update the setup process - so we don´t need to uninstall the previous
version manually
if we change the version we (vss makes this for us) create a new product code and
the upgrade code is the same - we don`t touch this

Improvement: Sync also State and PostOfficeBox, see Tracker item https://sourceforge.net/tracker/?func=detail&aid=3276467&group_id=369321&atid=1539126

Removed unnecessary constructors

Fix: set SyncDelete at every SyncStart to avoid "Skipped deletion" warnings, though Sync Deletion checkbox was checked

improved error handling for NullReferenceExceptions
