Minor updates, including:
- Converted templates import/export to use zip format (instead of xml/gz), so they can be compared using external tools.
- Added config settings for default cache timeout ("CacheTimeoutHours", "CacheTimeoutMinutes", "CacheTimeoutSeconds")
- Added BulkSelect methods to the 3 remote drivers (Wcf/Soap/Http). These can be used to preload the entity caches on a remote client app using a single call
