Bug 219483 [Markers] MarkerField needs to support font and colours
Some users want to be able to set the font and colour of an entry in the markers view. We should pass in a ViewerCell for this.

void updateTitle() {
		String status = MarkerSupportConstants.EMPTY_STRING;
		int totalCount = builder.getTotalMarkerCount();
		int filteredCount = 0;
		MarkerCategory[] categories = builder.getCategories();
		
		if (categories != null && builder.isShowingHierarchy()) {
			int markerLimit = MarkerSupportInternalUtilities.getMarkerLimit();
			for (int i = 0; i < categories.length; i++) {
				filteredCount += markerLimit < 0 ? categories[i].getTotalSize()
						: Math.min(categories[i].getTotalSize(), markerLimit);
			}
		} else {
			filteredCount = MarkerSupportInternalUtilities.getMarkerLimit();
		}
		if (filteredCount < 0 || filteredCount >= totalCount) {
			status = NLS.bind(MarkerMessages.filter_itemsMessage, new Integer(
					totalCount));
		} else {
			status = NLS.bind(MarkerMessages.filter_matchedMessage,
					new Integer(filteredCount), new Integer(totalCount));
