- Revision ID: edam@waxworlds.org-20110530153301-oor6ci9b3hf9clul
- refactored some code to do with how contacts are imported
- Vcards (and ContactData) instances now generate a CacheIdentifier when they are finalised so that ContactData instances that do not have enough information to identify them can be discovered then
- importContact() now calls the private method checkForDuplicate(), renamed from isImportRequired(), and return if it is not
- importContact() and checkForDuplicate() now use the ContactData's generated CacheIdentifier
- Vcards (and ContactData) instances now generate a CacheIdentifier when they are finalised so that ContactData instances that do not have enough information to identify them can be discovered then
