Changes to improve ScoreEntry performance on mobile devices

I've updated the ScoreEntry function so that it only does the form initialization functions once for multiple team scores. One of the most expensive operations was the activateElements function that processed the radio button inputs into jQuery stylized radio buttons.
I don't know if I can do much about rendering speed on slow mobile devices.

I noticed inconsistencies in referring to the score entry page. I believe I've corrected them by renaming Score_Entry.html to ScoreEntry.html and fixing up the Success.html to reference the new name.
