Update to latest note-c master. (#124)

* Delete .github subdirectory when updating note-c subtree.

* remove note-c before re-add

* Squashed 'src/note-c/' content from commit bbb727d

git-subtree-dir: src/note-c
git-subtree-split: bbb727d657aa4912e86620d874673e7a5680b53f

* Update to latest note-c master.

* Change references to JAddNumberToObject to JAddIntToObject.

JAddIntToObject used to be a macro for JAddNumberToObject. Now it's its own
function and takes a JINTEGER rather than a JNUMBER.
