Make the default "since" for the activity page configurable
Only set the 'tabs' template variable if there are actually tabs

This is useful for a custom theme for gitit that I'm working on, and it doesn't break the existing default theme, so I hope it should be fine.
Removed access question from password reset form, only for register form

This is the behaviour that I want for my gitit instance, I don't know if it's what other people want, but I think it makes more sense. I'm throwing it out there to see what people think.
Added for attribute to all the labels on all the forms

Revert "Create page if no match is found when using _go"

This reverts commit 1328545e1b9e86132b4937ac5fb2afc314bb0758.

I hadn't fully appreciated the loss of the old prefix-match behavior,
which was useful.  So for now I want to pull this change back.
(See #397 and discussion on gitit-discuss.)

Note that the old behavior copied wikipedia.
