WebSockets frame list displayed in WebSockets side panel should support keyboard navigation.

At least the following keys should be supported

• arrow key up
• arrow key down
• Home (move to the first)
• End (move to the last)

Support for keyboard navigation in WS frame list.

Prototype that works for me:

1. The patch is again using the PAGE_SIZE_ITEM_COUNT_RATIO. It's not nice, but good enough for now and the request list is using that too actually.

2. It fixes also bug 1576078, so we might want to close that one as dup

Please apply and test

Updated the patch!

Backed out changeset ae73cf1c7395 (bug 1561873) for eslint failure at FrameListContent.js on a CLOSED TREE.
