Entry consistency

[Berserker66]

Currently for a majority of mods, the info fields do not match up. That beeing the fields in the /mods json index and the info.json in the actual file.

For all current cases, look into https://travis-ci.org/Berserker66/FactorioManager/builds/82317559 and search for AssertionError.

It would be nice if added files are checked for actually beeing .zip's with info.json and enter the mod info automatically into factoriomods.com, as far as available. (I know for example categories would be missing).

Right now there are also 3 files:

broken_mods = {"5dim mod", "Air Filtering", "canInsert"}

That are not valid .zip's with an info.json, therefore fail on automated installs.
