Points from scoring flags

You get points from scoring flags now. Suggestion from mitchell, think
it would go well to give even more encouragement to get flags. Deleted
props now give you your points back, will work well with conserving
resources, meaning you can remove one thing to get another, problem
solving etc. Changed formatting of the alerts. Currently, a player will
get a set number of points at spawn, and a whole team will get a divided
number of points from collecting flags.
