* refactoring
* allow for creation of games as spectator
allow setting the amount of games per user to none
remove limit on amount of games when creating a game as judge as
spectator
* refactor common/server_player.cpp
* do not close games with spectating host automatically
* remove check that filters out 0 player games
this check didn't really do anything, deleted games are removed before
it would be reached
* don't transfer host to spectators
this seems to cause a bug, also present on master
* add a bunch of parents to dialogs
works on #3651
* use game as parent instead
* add more parents
* fix create token dialog modality
* add parent to game information window
* replace a bunch of nullptrs with the magic of sed
* add parent to tip of the day and counters
* reorder game ptr
* set parent for life counter
* clangify
