Required FS3 Code

While I tried to keep intrusions into core FS3 code to a minimum, some changes are required for the plug-in to work properly. These are changes you MUST make.

1. Required Code: custom_hooks.rb
2. Required Code: gear_helper.rb
3. Required Code: actions_helper.rb
4. Required Code: combantant_helper.rb

There are also some optional FS3 code changes that you can choose to make or ignore.
