helixhorned efdd31d5a9 Guard retrieval of player index (.yvel) from APLAYER sprite. 
It is unacceptable that yvel is on one hand modifiable without restriction from
scripting, but can be used as an array index without prior bound check in the C
code. Because that member has an overloaded meaning and is also used for
innocuous purposes such as the green color intensity of an SE light, it's
infeasible to restrict access from scripting. Consequently, we must add bound
checks on the C side. This is the first part of the effort to make .yvel safe,
adding two functions P_Get() and P_GetP(). There are a couple of other uses as
some kind of index.
