Transform PhobosLoader to a Scrape loader (4)

[DissectBot]

There is nothing specifically Phobos about the Phobos loader. The file extension it is checking on is just one of many possibilities. The rest of the loader is just generic scarping for extfs/NTFS.

It can easily be transformed to a generic Scrape loader. It looks like it then could become part of the fallback loaders. We need to discuss a bit about where in the order of (fallback) loaders to put it.
