Purge description formatting
At long last, this makes the Description: field get passed through unchanged to the index. The eliminates a lot of tangled, mystery code and makes the whole process a lot easier to understand. The end goal is to make fdroidserver a pipe that takes metadata and writes it to the index unchanged. Lastly, it drastically speeds up fdroid lint and fdroid rewritemeta when specifying appids since it will now only parse the .yml files that it needs to, rather than always parsing all of them.
