Added new stats to the fighter's pages.

Years Active = 1-15 (Let's you know how many years your fighter has been alive)


Recruit Date = This will tell you the game date your fighter was recruited to help manage your retirements better.


**Note for new camps = The first 4 fighters that you recruit will have wonky data as mkick coded in some weird restriction for new camps. I'll have to figure out how to alter that at a later date.


All new recruits should see proper Recruit Date and start with 0 Years Active but the existing fighters will have incorrect data unless manually adjusted by me. I'll attempt to manually adjust as many active fighters as i can but just know from here on the new stats will read correctly.
