Week plan calendar view

Upd.: some description of the current features:

+ you can change week view for 3 months: 1 month before, current month, 1 month after. This is to be modified in the future, probably, but at the moment gives enough room for better calendar planning;

+ current widget may be modified in future updates - from what we found, this looked like the only open-source library that was compatible with Android 2.3, the minimal version of Android we do support now. It is simple enough, so we might well stay with it;

+ goal view (and reminders) are not updated behind the basic view - this is the next step - to make the goals view use calendar settings, too. The goal view itself is a separate question - we don't like how it looks now, will most probably work on it;

Bugs

Upd. 03.06.2015: 0.15.1 with bug fixes is out.

It turns out that the latest version has a lot of critical bugs. Thus, the next release will be mainly about fixing them.

Among the bugs:
+ FC when you enter Notes in two-column mode
+ FC when you cancel achievements dialog
+ 'Now!' in Days/Priorities dialog does not refresh the data set
+ Pomodoro crashes on period change if the app is in the background
+ Project sub-actions does not get parent set (thus becoming simple actions) when coming from the Weekplan page
+ some more.

All of these were reported by you, either by FC reports or by reviews or by direct letters - thank you! And a special thank to one particular user, who constantly keeps giving us feedback almost after each update!
