Team becomes its own filter!

[Pablete1234]

Teams (for protos 1.4 and up) are now a filter for themselves. This means that anywhere a filter is expected, you can use the team itself.

<teams>
  <team id="red-team" ...>Red</team>
  <team id="blue-team" ...>Blue</team>
</teams>
<regions>
  <apply enter="deny(red-team)" region="..."/>
  <apply enter="deny(blue-team)" region="..."/>
</regions>

This will likely not work in 1.3.x proto as there you could already have teams and filters with same ids, so they don't share a context.
