Bring back pgm objective filters

[Pablete1234]

Current pgm only has support for the objective filter, and it is not properly documented over at pgm.dev.

We should bring back all 3 ways of parsing this filter (they all result in reusing the GoalFilter, just with different parameters in the constructor)

What 1.12+ pgm supported was:
Objective - Supports any="true" or team="team-id" - We have this already, although it is not documented.
<objective>goal-id</objective> - Matches if the team of the player is the one that completed it
<objective any="true">goal-id</objective> - Matches if ANY team completed it
<objective team="red-team">goal-id</objective> - Matches if red team completed it

Completed - Does NOT support any="true" or team="team-id"
<completed>goal-id</completed> - This is equivalent to <objective any="true">goal-id</objective>

Captured - Supports team="team-id" but does NOT support any="true"
<captured>goal-id</captured> - Matches if the team of the player is the one that completed it
<captured team="team-id">goal-id</captured> - Matches if the specific team completed it

This seems quite verbose and is probably like it is for backwards compatibility reasons, since the any="true" was added much later, and i'm assuming before you were just assumed to use completed if you wanted that behavior
They all in-code end up using the same GoalFilter with the same logic, just sometimes with a "hardcoded" team (or no-team, and checks all of them)

Footnote 1: in all places where i mentioned team i mean competitor, which means it works for FFA if you assume each "player" is a "team", obviously you can't specify a specific team in xml for ffa
Footnote 2: the filter never abstained in old pgm.

I got the first part documented in PGMDev/Website@8fefd12
So essentially, all these you described do the same thing as the objective attributes?

[Pablete1234]

yeah, they are the same as objective with the specific attributes
