Paginate Logs and fix log sorting

[Panaetius]

Logs in the dashboard can get very lengthy, leading to performance issues in most browsers.

Logs should be paginated (1000 entries/per page or so).

Additionally, new entries are currently placed at the end of the logs, meaning the user has to keep scrolling to keep up with the logs.

We could either invert the sort order (newest entries first) or we could add a "Follow Log" checkbox that automatically scrolls to the end when an entry is appended to the log. Either way, the newest entries should be on the first page of the logs.
