Subject: [PATCH] Document fork relationship with Notesium upstream

LICENSE retains the original Notesium copyright alongside librenotes.
NOTICE records the upstream URL, fork commit hash
(aff9f460c2d864112db7f0935b4168b107289d91), fork date, and
instructions for contributors who want to add the upstream remote
and cherry-pick patches.

Closes #36.

+Working with the upstream remote
+--------------------------------
+
+Contributors who want to follow upstream Notesium development or cherry-pick
+fixes from upstream can add the upstream remote:
+
+    git remote add upstream https://github.com/alonswartz/notesium.git
+    git fetch upstream
+
+To inspect upstream changes since the fork point:
+
+    git log aff9f460c2d864112db7f0935b4168b107289d91..upstream/master
+
+Note that the librenotes layout differs from upstream (sources moved into
+internal/notesium/), so direct merges will conflict. Cherry-picking
+individual upstream patches is the expected workflow.
