Fixes for NHL

[cameronkeif]

Fixes a few bugs I noticed with the new NHL functionality from dcd323e0a85dc9d942dcb4374fc0cfe104660e38:

• Goalies were not being updated, because they are in a separate tbody.Table__TBODY element. This is also true for baseball pitchers if that's ever implemented.
• The extension was hardcoded against F slots, but did not work for separate forward positions (C, LW, RW).
• Unknown slot errors were caused by what looks some old code that was moved to the NBA config, but wasn't removed from the root autostart.js (the parseSlotType(...) function)
