Period navigation controls for summaries

[em411]

I would like to suggest adding period navigation controls (previous/next buttons) to the summary view in Wakapi. This would make it easier to browse through the historical data without having to manually change the dates.

Current behavior:

Currently, to view summary for other than predefined period, user needs to manually enter date for both Start and End fields.

Proposed Solution:

Add prev/next navigation arrows (←/→) next to the current period display, which would allow users to:

• When viewing daily summary: quickly jump to previous/next day
• When viewing weekly summary: quickly jump to previous/next week
• When viewing monthly summary: quickly jump to previous/next month

Benefits:

• Improved user experience with faster navigation between time periods
• Reduces number of clicks required to view adjacent time periods

I like that idea! Could probably be implemented in a fairly lean fashion with a few lines of JavaScript. Only thing I'd like to ask for when implementing this is to make these new controls slim and seamless.

FYI: on the summary page adding interval=last_month to the request parameters works perfectly.
