Allowed Grouped view tables to show as expanded or collapsed by default.

[sashaluxdev]

Right now, if you set a table view to be "Grouped by X" it shows a max of 8 records per group before having you click "Load more" to show another 8 records. For groups that have hundreds or thousands of records, this is very cumbersome. A simple toggle in the Group view settings to configure the default to either collapsed (current) or expanded would make the feature much more usable for large datasets.

Better (more complex) solution; allow users to set the "Default visible records per group" with options for 10, 25, 50, 100, or All.
Or something along those lines.
