Lots of small improvements

• saving projects
• adding/removing tags to tasks
• get workspace by id (to get is_organization)
• continuing implementation of async Tasks
• serialization flags for AsanaProject
• constructors for AsanaProject
• Move the IsFaulted code to the correct place
• Support serialization
• AsanaTag constructor
• AsanaTask fixes
• Refresh() for workspace
• CreateWorkspaceTag for saving tags

I've added more useful stuff:

• IsOrganization is nullable
• Implemented Delete functions and missing Update ones, eg.

asanaObject.Delete();

• Cast operators, eg.

Int64 projectID = 1234;
AsanaProject project = (AsanaProject) projectID;

• Constructors (useful for caching objects into files / serialization, recreating the objects by ID)
• Alternative (more universal) way of calling Get functions by Type (old one generated too), eg.

public static void FetchByIdOneOf<AsanaObjectT>(Int64 ID)
{
                            AsanaObject asanaObject;
                            AsanaHost.Get<AsanaObjectT>(ID, asanaReturn =>
                            {
                                asanaObject = asanaReturn;
                            }).Wait();
                            return asanaObject;
}
var outputObject = AsanaFetchByIdOneOf<AsanaProject>(1234567);

This was, again, useful for writing caching functions in an extra library I created (so I don't need to repeat all of the code for each Asana function). Might release that as a separate project. Caching both into memory and files.

Please comment if you don't understand something or if you think something could be improved.

This looks good to me. Thanks Bazyli :)
