GO Contact Sync Mod Code

Enabled NotesSync after Workaround has been found

IMPROVEMENT: added NotesSync (not finished yet)
FIX: Fixed some NullPointerExceptions

Support large Exchange contact lists, get SMTP email when Exchange returns X500 addresses, use running Outlook instance if present.

CHANGE 1: Support a large number of contacts on Exchange server without hitting the policy limitation of max number of contacts that can be processed simultaneously.

CHANGE 2: Enhancement request 3156687: Properly get the SMTP e-mail address of Exchange contacts when Exchange returns X500 addresses.

CHANGE 3: Try to contact a running Outlook application before trying to launch a new one. Should make the program work in any situation, whether Outlook is running or not.

OTHER SMALL FIXES:
- Never re-throw an exception using "throw ex". Just use "throw". (preserves stack trace)
- Handle an invalid photo on a Google contact (skip the photo).

Switched from old Google API (v1.0) to new version (v2.0)

Fixed several issues regarding timing problem and contacts that are updated again and again (e.g. by setting a TimeTolerance to 60 seconds, because lastSync is saved without seconds anyway

replaced AppDomain.CurrentDomain.BaseDirectory by Path.GetTempPath to enable also users without write permission to the installation path to sync photos
