Moving the dashboard to the Network Admin area
Removing nonce from log search form

Having the nonce made it impossible to deep-link to the log entry in e-mail notifications, since the nonce would be generated by the user whose action triggered the notifcation, but the link that included the nonce was intended to be viewed by admins. Since the nonce wasn't assigned to the admins, it would fail verification.

Having nonces on a search form is probably overkill anyway, since it's only returning data, rather than making changes to the system state.
Limiting log id search to a single page

Previously 51 results would be returned if per_page was set to 50, which triggered pagination. Limiting the results to a number lower than per_page ensures the results will only take up a single page.
