Create user preferences to set default table page size for tools

Several tools, including Announcements and Assignments, include a Show Items dropdown menu at the top of the page. By default, the menu displays 10 items and can be adjusted to display up to 200 items; however, each time the tool is reloaded the default item display is reset to 10 items. This can be confusing for users who do not immediately recognize that additional items are included in the tool but are located on a subsequent page.

This is a request to create an option that would allow users to set a custom default item display option for the Show Items dropdown menu.
