Clever default behavior for batch and parametric table and plots

[butlerpd]

It is now easy to add error bars on the batch parametric plots. Since in most cases the fit parameter being plotted has an associated (default hidden) error column, it would be nice to have some more intelligence such as autoplotting of associated error and auto renaming columns in the selection range when a column is inserted (i.e. I[2:18] becomes J[2:18] when a column is inserted before I.
