Ability to to end a poll

[OLLIWest]

Two suggestions/observations from using your polling function:

1. Allow creator to enter an end date so people are not allowed to "vote" after a certain time period.

2. The CSV export has a bug OR needs information added to it. If a reader makes a selection on the poll then returns a day or more later and makes a selection again on the same poll, the app view shows the last date they "voted" but the exported CSV only shows the first date they "voted." I think both of those pieces of information should be in the report.

Yes. Polls need an end date... there are always some voters who will vote even after being told that the poll is closed. Having an end date helps to address this issue.
