Update outdated unified repositories

[SinTh0r4s]

• Add/Update GitHub CI
• Update build.gradle
• Update .gitignore
• Strip dependencies, if transitive
• Fix dependency versions? (discuss!)
  • Option to use dynamic versions (example compile 'org.springframework:spring-core:3.0.+'). It might update to newer versions, but will skip untagged dev commits. Benefit: Stays more up-to-date. Negativ: A tagged commit can still break the system, yet it is less like because it is specifically choosen
• Remove transitive dependencies if the mod depends itself on it and define those again. This will prevent outdated or changed transitive dependencies that mods itself depends on.
• Add names to repositories
• fix username (remove quotes)
