[laasker]

Describe your feature request or suggestion in detail

Rename the config Solo.3v3.FilterTalents to Solo.3v3.FilterRole and edit it to have multiple options:

FilterRole = 0 (keep the way it is, no restriction of melee/ranged/healer, teams can be formed of 2 melee, 3 melee etc)
FilterRole = 1 (keep the way it is, team can only be formed by 1 melee/1 ranged/1 healer per team)
FilterRole = 2 (new function! - make it need atleast 1 healer per team, so teams can be formed of 1 healer + 2 melee or 2 ranged, or 1 melee and 1 ranged)

All those kinds of things, perhaps, can be added, to the extent that the base module works. Once we have it working, it can be configured to add this type of things, or perhaps others that arise. For now, the priority is to make it work in its base form.
