Merge components-api JSON Schema in one file

[taorepoara]

Merging the components-api JSON Schema files into a single file would make it easier to use in many parts of the project.

It also make easier the language libs for the app creators because some of the libs only manage a single.

In order to make it easier to write we can keep them like they are and merge them at build time.

Done with a custom project since i've not found any project to do this.
