Fix injury duration

I feel The weeks injured needs to be addressed. 

Case in point, my RB was injured in week 11 and was going to be out for 29 weeks. 
The date for the game was early November, so clearly the player is out for the season, but 29 weeks from November should be May-June. 

instead the game only counts weeks advanced, so when the next season starts in September, they player is still out for multiple weeks. 

i feel like this is really a matter of revising a conditional table that indicates how many weeks should be deducted by the start of the following season (if player has X weeks of recovery remaining by week zero, he is no longer injured).
