Remove "used" parameter from inject function

[jobe-m]

Since references to the inject objects and mappers are removed after initialization of the world and all systems we can remove this parameter again.
The idea for that parameter was that an injected object could be referenced (the first time) at a later time after initialization. But I think that it is much cleaner (how it is done now) to delete the inject object references after they where checked if they are all used.

I will bring in that change when I bring in the DSL to the next branch. Should be possible until ~Thursday! I will notify you when everything is ready.

edit: by the way, they also released Kotlin 1.7 but I think we should wait for the first bugfix release because I am pretty sure there are bugs in it again (as always ;) ). So let's wait for 1.71 or whatever they will call it before we upgrade. OR at least wait ~4 weeks before we upgrade.

No problem. I am not in a hurry with the kotlin compiler. And yeah, first major versions might have still nasty bugs ;)

I will close the issue. It is part of #53
