OGDI DataLab v5 Updates and Improvements

OGDI DataLab v5 is a merge of two branches: OGDI DataLab v4 and OGDI v2a France which includes several improvements and addresses multiple bug fixes.

What's New at a Glance

• DataBrowser now runs in the same Web Role as the DataService (1/3 Azure cost savings) by default. DataService is on port :8080, but having a dedicated Web Role for DataService is still possible with minimal code to reconfigure
• The DataBrowser is fully localized in English and French depending on browser language (English is the default language for other languages). Additional languages can easily be added via resources files
• The solution now provides a basic implementation of the W3C standard RDF for the both the DataLoader and DataService. It can be seen as RDF over OData (v5)

Updates / Improvements compared to OGDI v2a:

• Updated Charting Components (included in .NET 4)
• Removed Dependency to WPF Toolkit (Most of those features were added to WPF in .NET 4)

2. Updated to Windows Azure SDK 1.3, then again to SDK 1.6.
