Sanitize user input in discord to prevent odd formatting issues.

DiscordSanitizationHepler.cs

	public static class DiscordSanitizationHelper {
		private static char[] NeedsSanitation => new char[] {
			'\\', '`', '-', '=', '[', ']', '\'', ',', '.', '~', '!', '@',
			'#', '$', '%', '^', '&', '*', '(', ')', '_', '+', '{', '}', '|',
			':', '"', '<', '>', '?', '/',
		};

		public static string DiscordSanitize(this string input) {
			var output = input;

			foreach (var i in NeedsSanitation)
				output = output.Replace($"{i}", $"\\{i}");

			return output;
		}
	}
