Fixed a minor issue which in rare cases caused calendar data for preview ("Show calendar content") to be downloaded from cache with incorrect location data.

Added new country, Philippines. All events are in English. Contains all the standard calendars, including Holidays, Flag Days & Good to Know days.

Fixed a bug where the user's selected location (for example, in Holidays) would not affect on the holidays shown to him. Now, for calendars which have location-dependent holidays (such as US states), only holidays for own state or the whole country are shown.

Added a command to recreate subscription identifier. When the subscription is updated at WebCal.Guru, Google Calendar often does not download the new subscription until later. Update can not be forced by the user. So, the user must either just wait, or regenerate a new ID, re-subscribe to Google calendar with the new id and then delete the old subscription. WebCal.Guru can't force Google Calendar to update their cache.
