SSP-2716 Inline coach history report handler

Previously the coach history report link handler was in the
Main tool's codebase so, the link had no effect if the tool
wasn't currently focused. The patch simply moves that
handler into the controller for the panel that houses
the link (StudentRecordViewController.js) so the handler is
effectively always available.

Note that this patch for 2.5.x is slightly different than
the 2.6.x patch in that StudentRecordViewController did not
have a reference to the person singleton in 2.5.x so it
needed to be added as part of this patch (it gets it in
2.6.x as part of the Watch Student enhancement).
