Changes

Update partially extremely outdated README.

It seems noone really took care of it over the past years.
There was a fair bit of use of the future tense even that
dates back to the first commit ever made to this project:
Who would have thought that this actually would end up
going anywhere. Well, here we stand proudly at last
and can use the present tense.

That being said, we stand at a metaphorical crossroads,
where all possible futures diverge from, but even more so
all possible pasts have converged to. While I (sadly) know
from which past we have come from, I dearly hope that the
future of mine, and thus by extension the future of the
Galimulator modding world, are separate. So, so long and
farewell? Probably not that quickly though, but the final
judgement will arrive over the coming months. The first
judgement will come tomorrow however (I'm visiting the
college ["Hochschule"] where I'll be studying at for the
next few years tomorrow - I'm super excited even though
that makes no difference since no people I'd realistically
will be friends with will be present, nor is it like I
can fundementally change my decision. But still, it's
important to know whether the "canonical" "I" vibes with
the place; Otherwise I might need to /slightly/ alter who
I am. Probably won't be that much of an issue, right?).
