Remove the parameter defaults for the AzureTableRepository since they are never used (interface defaults get used instead).
Increase the interface default to something high (Azure storage can pull 1000 at a time).  Should eventually move this elsewhere though since the interface shouldn't be aware of the capabilities/limitations of the specific implementations).
Modify the IdeasController to be able to search across repo pages of data to assemble a single API page of data based on the tags that are specified.
