Comp Update Bug Fixes

[larissar]

• Fixed a bug causing horses to not get added to the renderer on time when users are in breeder player mode, re-wrote how age based trigger is handled, added code for fixing horses missing their images
• Fixed a bug not allowing horses with greater than 10 starts, and lots of training, from being able to enter lower level shows if they have poor points-per-start calculations
• Fixed a bug with local shows also not correctly calculating a horses show level after they have more than 10 starts
