SimpleDataSelectorType - Performance and Usecase trouble

[jycamier]

When I use SimpleDataSelectorType on edition mode :

• the option max_results is set with the default value 100 ; if I edit a content with a relation not in the first 100 results of the linked entity, the relation displayed is wrong ;
• if unset max_results to get all linked entities, there is a huge problem of performance (a huge number of requests).
