Fixed JSON. Added draw method. Added priority select's coloring functionality. Added new settings in JSON to set up dates.

------------------------------------------------------------------------------------------------------
Added TaskManager .drawAll() method which:
Draws:
		A) 	Tags selector if:
				1)Tags functionality is enabled in settings.json
				2)Count of tags more than zero,

			Otherwise all tags adding with tag 'All'.

		B)	Priority selector if:
				1)Priority functionality is enabled in settings.json
				2)Count of priorities more than zero,

			Otherwise priority selector is hidden and there is no value of priority inserted;

Maintaining priority selector to change background-color to appropriate color from settings json.
Draws date selector orienting to settings.json

------------------------------------------------------------------------------------------------------
Removed keys: tagsCount and priorityCount form settings.json (now count is calculating in JS file with .length property).
