ScriptNode unsaved change tracking.

ScriptNode now has an "unsavedChanges" BoolPlug which is kept up to date when Actions are performed and when the script is save()d or load()ed. This will form the basis for UI elements preventing the user from accidentally losing work when closing windows or quitting. Additionally ScriptNode plug accessors now use the much faster index based accessors rather than name based lookup and unecessary member data.
ScriptWindow close icon and ApplicationMenu Quit item both now prompt the user before discarding unsaved work.
Hiding unsaved changes plug in the Settings... window.

Prompt user when exiting would lose unsaved changes.
Scene reader/writer now convert the context time to seconds using a hard coded framerate. Also removed the SceneReader::cache() in favor of IECore::SharedSceneInterfaces, and made the reader ignore a couple of attributes automatically written by the SceneCache, to fix a test failure

Merge pull request #71 from davidsminor/master

small SceneReader/writer updates, + a branch in SceneProcedural that renders VisibleRenderables
Fixed graphical glitches caused by icons overlapping the edge of the editors on the Gnome desktop. Removed style-setting code from SelectionMenu because it will now inherit the same style from the application.
