Make more columns sortable

[PhyxionNL]

Right now only .../events can sort by Date (asc/desc). However, there are more cases where sortable columns are useful. Some examples:

• .../users: first/last/events columns. For error, log, 404, usage, all.
• .../frequent: first/last/events columns. For error, log, 404, usage, all.
• session/events: created/duration columns.
• status/...: first/last/events columns.

This would be a great addition, I think this is already tracked by an issue (will double check). We'd be willing to accept a pr for this too :). It would be really hard to do a sort on users though... This is computed after the fact but anything is possible

I meant sorting by the dates and occurrences, on the /users and /frequent pages, such as type/error/frequent and type/error/users.
