G.C.Loader -> G.C.OldLoader, new G.C.Loader! fixing the overcacheing bug on corpus tabs. also kill some warnings

[DEBUG] swap G.C.DocsTable.renderPage for new function `page` and corresponding `pageCpt` to make the component a top level object instead of dynamic based on closure. Did not fix the problem, but improves the code somewhat

minor refactor of DocsTable. instead of reloading endlessly, we now rerender endlessly, which is easier to handle
