Gh-6: Migrade to gradle

[nicolube]

Implements #6 gh-6

[nicolube]

I beleive the how setup logic belongs into a gradle plugin, not build.gradle, but I think, it is fine for now.

[nicolube]

No, it does not, I will add the needed replacers

[nicolube]

@ItsNeil17 I'm not that fast... You just created the confilct by merging #5 xD

[nicolube]

Well that should do it...

[nicolube]

Well I replaced the json thing form the other repo with blossom since the custom func was not building because of some serialization build cache error.

[nicolube]

Also it was not my goal to migrate this repo to kotlin, the other had the hole kotlin std lib inside

[nicolube]

Ahh I see, it was migrated into a plugin...

id("app.ultradev.hytalegradle") version "1.5.3"

Seems to be this repo:
https://github.com/MrMineO5/HytaleGradlePlugin/

[nicolube]

@ItsNeil17 It is now migrated to the hytale gradle plugin
