option to load more per single page

[liesislukas]

would love to have option to load 100, 300, 500 or 1000 or any number of rows per page. While local development i would just go and load all rows quite often, while working on some unit tests and just want to see how data is set/fetched etc. and have a view of all data generated by test. Yes prior running the test i just erase all data in such case.
