Added include.js for use in non-browser.xul windows to bring in the SCHOLAR_CONFIG and Scholar objects
Adjusted sidebar to use shared object
Added test line (displayable by clicking "Hello, World" before and after sidebar load to demonstrate cross-window access
Fixed object retrieval queries to use orderIndex is 0 rather than 1, since that's the default now
Scholar_Objects.getAll() now uses loaded.push() rather than loaded[objectID], since _for (objectID in objects)_ isn't an option with treeview
Scholar_Object.getField() now returns an empty string rather than false for empty values
