Fix inconsistent spacing and trailing commas in objects in src/core/ files, so we can enable the comma-dangle and object-curly-spacing ESLint rules later on

*Unfortunately this patch is fairly big, even though it only covers the `src/core` folder, but splitting it even further seemed difficult.*

http://eslint.org/docs/rules/comma-dangle
http://eslint.org/docs/rules/object-curly-spacing

Given that we currently have quite inconsistent object formatting, fixing this in *one* big patch probably wouldn't be feasible (since I cannot imagine anyone wanting to review that); hence I've opted to try and do this piecewise instead.

Please note: This patch was created automatically, using the ESLint --fix command line option. In a couple of places this caused lines to become too long, and I've fixed those manually; please refer to the interdiff below for the only hand-edits in this patch.
