Subject: [PATCH] Adds new keyboard shortcuts to add sibling and child tabs.

Alt+Shift+I creates a new sibling tab of the current tab.
Alt+Shift+O creates a new child tab of the current tab.

I separated out two functions to create sibling and child tabs of a
passed tab in the utility functions section. These could be used in
other shortcuts/menus.
