add two methods to check for this week's parasha

[Elyahu41]

These methods were helpful to me because I just wanted to know what to read for Shnayim mikra weekly. The other getUpcomingParasha method will confuse people, in my opinion, because it will return a parasha in a week or two from now when the user might want to just know if there is a parasha this week or not.

There is also a second method for getSpecialShabbos

@Elyahu41 . Have a look at getUpcomingParshah()

[KosherJava]

@Elyahu41 , the name needs more clarity (I think). getUpcomingParsha is very similar, with the only difference being that this will return null if it is YT. We probably want to overrride getUcomomingParsha() with a boolean to control this, and we can deprecate the one without a parameter for removal in 3.0.

[Elyahu41]

I understand. How about something like this:

	public Parsha getUpcomingParshah(boolean thisWeek) {
		JewishCalendar clone = (JewishCalendar) clone();
		int daysToShabbos = (Calendar.SATURDAY - getDayOfWeek() + 7) % 7;
		if (getDayOfWeek() != Calendar.SATURDAY) {
			clone.forward(Calendar.DATE, daysToShabbos);
                if (thisWeek) {
                return clone.getParshah();
                }
		} else {
			clone.forward(Calendar.DATE, 7);
		}
		while(clone.getParshah() == Parsha.NONE) { //Yom Kippur / Sukkos or Pesach with 2 potential non-parsha Shabbosim in a row
			clone.forward(Calendar.DATE, 7);
		}
		return clone.getParshah();
	}
