better undo possibilities in trac wiki

[ThurnerRupert]

To make it easier to illustrate, take MediaWiki as an example: it has an "edit" and "undo" link on every entry in the history (​history example), and also on the difference displayed (​diff example). Pressing edit opens the old revision, save saves it as current. The undo link only works if one wants to undo the last edits.

MediaWiki also displays diff links to the previous, next, and current revision if an old revision is displayed, see here: ​example old version.

It features also an extension to undo everything a vandal did, see ​http://www.mediawiki.org/wiki/Extension_talk:Nuke.

Interesting suggestions, but the best method to fight spam is really to try to avoid it in the first place, and for that the SpamFilter is invaluable. We have around 1 to 5 spam per minute here on t.e.o, yet only a handful pass through the filter in a week, so I'd say it can be pretty effective.

Showing the Previous Version / Next Version links when looking at an old version is already what we do.

The "nuke" suggestion is interesting, but that could well be done in a plugin.

(btw., speaking of MediaWiki and Wikipedia, have a look at ​Wikipedia:Capitalization, following those futile conventions really improves readability…)

And "undo" feature would also be useful to undo changes that, while not necessarily spam, were still stupid.

Actually I'm not sure how the edit/undo suggestion improve anything over what we already have. The "nuke" thing sounds similar to #1120.
