ADD option to specify which calendars are shown, when "Show events that ended recently" is enabled

[allanlaal]

Use case:
I need to see X hours in the past (now supported thanks to #122 ), but I also have lots of calendars that should not show past events, like my weather calendars, sunset-sunrise and some shared calendars.

so if the option "Show events that ended recently" is not disabled, then one should be able to tick 1...N checkboxes for each of ones calendar to show past events for.

@allanlaal Your request made me look again at currently available Setting. And I realized that what we have as a separate "Calendars" settings "header" should be actually a part of "Event filters -> All events" settings section
Looking at calendar list this way, you are proposing to add another filter to "Event filters -> Past events" settings section.
Title: "Calendars, from which to show Past events"
...
?!

@yvolk yes, that is correct

In order not to overload one app with lots of features I think that you better create a separate widget with its own set of selected calendars and filters, and place it separately (maybe on the same screen...

?!

BTW, please try the latest beta at #320

@allanlaal There is no end to similar improvements. One may need to have different period into the future for different calendars, other settings, depending on a calendar.
Technically - no problem, but it makes the app far more complicated for ordinary Users (about 6 thousands of active users in Google Play only, and increasing...)

@allanlaal It came to me that we can really think about several "virtual" widgets, each with its own settings (excluding Widget Header, which will be the same...), but shown in the same visible home screen widget... but does anybody need this, except you? :-)
