More Link on month view not displaying in some cases

Since the display of the day's events does loop through every item, I added a variable that gets set when it reaches one of these events that will not be displayed. I can't completely grok how the $cur_cnt and $total_cnt are not working perfectly in some cases, so this finds exactly when something will not be displayed and adds a "more" link then. I don't have the time to roll it as a patch against the dev right now, but I'll try to come back to it later this week if I have time.

Updated issue summary to note that the example has now been updated with the fix above.

Applied the code to 7.x-3.5 again and it fixed the issue on the same site again. Thanks for testing it as well and rolling the patch nmillin!
