File manager integration: MD5 checksums, et al.

I’ve added a boolean for Rollator’s ‘file manager’ to allow one to turn on, or off the runtime MD5 checksumming of files against the SQL database.

I like having it on, but the truth of the matter is that this is taxing of system resources. In a perfect world, one might be able to assume the end user would be able to do this on their own – but most likely won’t.

I’ve turned it off for my own downloads, at least for now. I don’t trust caching of local files, and I am certainly not going to create a function to ‘update’ the MD5 checksums of the files, then have the SQL database test against itself – that’d just be an exercise in futility. ;)
