OM-150: add missing SVG tags
pass ::index to :fn if available
OM-152: eliminate om.core/graft

Add *cursor* dynamic var. Add IGraft marker protocol to differentiate
from proper cursors. Make om.core/graft private. Bind *cursor* in around
render implementations, only set if given non-graft cursor. In
om.core/build automatically graft cloneable non-cursors.
don't need to destructure shared
move watch key up
ignore .js files
go back to 2173 for now
OM-155: multiroot & :tx-listen incompatible

Modify private INotify protocol to include listen/unlisten methods. When
setting a root on an atom establish INotify methods if not present. In
om.core/root tear down if user re-evals.
add session
add unmounting example/test
add ICursorDerive protocol, allows derived cursor to be customized by
the original cursor in a parasitic way.
ICursorDerive parasitic test
document :ctor option to om.core/build
add om.core/rendering? predicate

Useful in IWillMount when establishing code that may run sync with
render the first time and async afterwards.
