Rework buttonbar label visibility based on viewport

[brianlove]

Adjust the visibility of the labels for the Reset, Download, and Column buttons based on the available space in the buttonbar. Download's label will hide first (still accessible to screen readers), followed by Add/Remove Columns, and finally Reset. If not enough space is available for the "Viewing X of Y..." text and/or buttons, they will wrap onto the next row of the buttonbar.

Closes #464
