Code Generation and T4 Text Templates

[kccarter76]

Is your feature request related to a problem? Please describe.
As a developer, I want the ability to add SubSonicContext to my project via the add wizard and use a T4 template to generate classes and the database context for me.

Describe the solution you'd like

1. On the solution explorer right click a folder location and go to the Add -> New Item
2. Under Visual C# Items -> SubSonic
3. Data Context, should appear as an option.
4. when selected, wizard is started that allow the user to configure the following:
   • database connection, db name and the default schema.
   • schema name that contains user defined table types
   • default schema is "dbo"
5. once confirmed, a T4 template is added to the project and using the connection:
   • Generates the table, procedure and view partial classes, if possible by convention mark a table with a corresponding defined table type.
   • If the generated class can not be marked with a defined table type, a non generated partial class can be used instead.
   • Generate SubSonic Data Context partial class
     • Context will contain ISubSonicSetCollections{TEntity} for each table and view.
     • At this time do not override OnDbConfiguring and OnDbModeling, will be implemented in a non generated partial class.
