Sort table in place

[jonbirge]

Right now the table is augmented with geolocation and blacklist data dynamically in HTML, which makes it hard to sort it without redoing the entire process. The current approach is done to get the user data ASAP, and then geolocation lookups are done asynchronously at the client.

The right way to do this is to assign an ID to each table row in the DOM and do the sort as follows:

• Read the sorted column into a JS array
• Sort it and create a permutation array
• Generate a new table in memory by reading the DOM rows in the right order
• Replace the DOM table with the table in memory

This approach will allow the table to be updated without having to create a persistent JS data structure to represent the table redundant with the DOM, yet allow the update to happen atomically to avoid display issues or thrashing the DOM.
