Showing a bucket's budget and spending without the date range

[mlaitinen]

I'm evaluating Buckets as a budgeting tool for private house construction. It has pretty much everything I need, except a view for analyzing the budgeted amounts and spending of a single bucket without date filtering. This would allow a quick overview of how much was originally budgeted, at what stage and why the budget had to be adjusted, and how much was spent overall.

This probably wouldn't make too much sense for a long-running standard budget (i.e. for groceries or rent), but for a fixed-term project with a start and an end dates it would be really useful.

So the idea is to allow selecting a custom date range, or "all dates" in the single bucket view.

It almost seems like something like this has already been worked on, because when I type in an invalid value (e.g. 1) to the year selector, an additional graph becomes visible:

I can definitely see the need for this (and have wanted it myself many times). This is related to #163 and #262
