Remove all but a single line break at the end of the imported CSV

Whenever pasting from Word into the editor inputs, styles (fonts, text-size, etc.) are being pasted as html, usually from text as a span.

The real problem is how messy the new HTML and styles are. Style properties are not allowed on child elements of the table element, only classes. The whole point of this tool is easy and clean html, after all.

It will likely be easier to disallow formatting to be pasted somehow, instead of trying to match it.

This will need to be done on paste (into the input), or maybe inputs support this out of the box somehow.

Unexpected behavior when importing some CSVs and some tables break on export. This is likely due to improper CSV formatting/reading. Needs investigating.

reload.js is causing a circular depends warning in the terminal on bundle. The effected files are controls.js, colgroup.js, header.js, body.js, footer.js.

reload.js calls createTableEditor, which is read as being inside of createTableEditor's scope by rollup. Requiring createTableEditor in reload.js is what causes the circular dependency warning.

As createTableEditor can never be invoked inside of its own scope (it is passed on to an eventListener) this is probably OK. However, it would be nice to either come up with a different design to reload the editor (or to ignore the warning and move on with my life).
