Some bugs

[AndroidDeveloperLB]

1. Choose "all day" sometimes set it to be 2 days. From the current one to the next.
2. Choosing a customized date for a new event turns off the "all day" toggle.
3. Pressing "today" multiple times does multiple scrolling without a reason.
4. when fast scrolling , it always gets to the end (or start), and then loads extra pages.
5. weather forecast doesn't work at all.
6. Pressing back when the month-view area is opened - doesn't close it. It exits the app instead.
7. App crashed when scrolling around in the months-view. log:

8. As opposed to Google's calendar , touching outside of the month-view doesn't close it
