Adds a context menu to selections with Georgia Tech class numbers
When you select text on any webpage, if it contains a full course identifier (like "ME 1770"), right-clicking the selection will add a context menu entry to go straight to the Georgia Tech OSCAR page for the Fall 2016 semester.
If the selection only contains a four-digit number, the context menu entry will lead to a search for all classes with that course number.
