Address width and scrolling in Shiny apps

[amoeba]

edit_biblio, for example, gets really wide and unwieldy. We might use another approach there or at least find a way to keep the help documentation visible while you scroll.

Looking into this today, it seems like handsontables does some behind the scenes work that makes it a bit trickier than just setting a CSS for the table.

We can turn off AutoColumnSize by passing colWidths = '100px' (for example) to rhandsontable::rhandsontable. I think it would be preferable to leave it dynamic with the caveat of limiting a maximum width, but unfortunately that does not seem possible at the moment (see here).

I haven't been able to work around handsontable to set a maximum width when we are editing a cell (css handsontableInput).

One challenge I'm noticing with a fixed colWidths is if your columns are filled with lots of text, the horizontal scrollbar gets lost at the bottom of the page..

I opened a PR with the colWidths approach for you to test if you'd like (#113)

Another totally alternative idea I had was essentially transposing the CSV to scroll vertically through the different fields - this might actually be an easier way to visualize and input the data. Would just require more data manipulation.
