Create a JSON file describing the releases on the website

[KOLANICH]

It may be useful for building binary packages from the binaries published. Should contain:

• a version of schema
• an array of versions (the latest one has index 0)

Each version object should contain:

• a name of version
• the date of its release
• changelog
• an object of variants descriptors with the following keys:
  • installer
  • portable-zip
  • portable-7z
  • source

Each variant descriptor is an object of files descriptors with following keys
* i686
* x86_64
* source

Each file descriptor is an object containing:

• a link to the file
• a secure enough hash of that file

The JSON file is signed, the signature is published alongside the file. The file is generated locally on the machine of the person making the release (a script appending a new release to the file would be needed).
