Add option to Choose MAX results

[jdeck88]

Some users on slow connections may want to limit to less results (e.g. 5,000) than the current default while other users on fast connections may be OK with much more (e.g. 90,000). More than 90,000 i worry about performance concerns.

Create a dropdown to set Max Results:

5,000
15,000 (default)
30,000
90,000
