Handle archives with temporary files instead of serving them from memory

[theobisproject]

I'd like to have feedback on this since the description mentions the goal of not having temporary files with the project.

When handling archives in the 2 digit gigabyte category the amount of RAM needed to serve those files is not what we have available in our application. Also there are some compression formats (bzip, gz) which do not allow random access and therefore we would need to either cache the content of those files or reextract them every time.

I would propose to add a user definable property when creating the filesystem where the user can configure the wanted behaviour (in memory or temporary file).
