Create document to track system contract functions changes

[lukelee-sl]

Problem

From time to time, we need to make additions to or more importantly make modifications to the function signatures for system contracts. For example, a new parameter might need to be added or the parameter type might need to be altered (eg. uint->int). Create a document that keeps a history of these changes would be beneficial to existing and new developers.
