Let me decide if I want the cursor to focus on the search box or not

Problem/Motivation

When you load the module page with module_filter enabled, the cursor automatically places itself in the module search box. This prevents me from using my keyboard arrow keys to scroll down. I have to click outside the search box to remove the focus first.

Proposed resolution

Add a configuration option that lets me stop the cursor focus from starting in the search box.

I'm asking for a configuration option because I can see how the default behavior is useful for many people. Having an option lets people set it up how they want it. Whichever way is most useful for them.
