Save downloaded DB archives to disk before unzipping#700

This fixes two classes of DBs that can't be installed directly from downloading: 1. DBs whose central directories do not align with their file headers. We need to download and save the entire archive before we can read the central directory and use that to guide the unzipping. 2. Large DBs require too much memory so can't be downloaded and unzipped in a single stream. We also add proper progress notifications to the download progress monitor so users are aware of how many more MBs are left to download. It's not yet possible to do the same for unzipping using the current unzipper library, since unzipping using the central directory does not expose a stream.

LGTM. I tried to resolve the merge conflict in the ui but have realised it would have probably been cleaner for you to rebase instead. Feel free to remove my merge commit and rebase instead.

Actually squash and merge will do the right thing. |
