Add support for filtering WorkBench columns

[grantfitzsimmons]

I have often needed to filter spreadsheets, but I must pre-process the data in Excel before importing it. This has been mentioned before. Since Handsontable, the spreadsheet library used by Specify, supports filtering natively, we should enable it.

Filtering lets you quickly find the information that you're looking for, based on specific criteria. This makes data analysis easier and faster, especially with large data sets.

Handsontable's built-in filtering interface resembles Excel's, so it's intuitive even to non-technical users. And if you want to implement your own interface, you can easily filter data programmatically, using Handsontable's API.

You can filter data by value, or use the built-in conditions, which are different for each of the available column types.
