Connect through desktop application (local vault files)

[perry-mitchell]

Option to connect to archives available in the desktop application.

Once an encrypted channel is set up, access to the filesystem can be provided. Files read and written should be limited to .bcup files only.

This would be particularly useful as the browser app only allows connection to remote/cloud stored bcup archives, as current.
The alternative would be to have to specify the local file directly in the browser app - if they didn't want to install the desktop application. Of-course, they'd have to manage the sync themselves.

I really need this too; working on restricted network environnement I can't connect to external network...

I've completed the file host library that we'll use for this feature: secure-file-host

It needs to be implemented in the Desktop app, and then connected to from the extension: buttercup/buttercup-desktop#678

[perry-mitchell]

This is now complete in #193. It'll be released shortly.

Is it possible to extend this feature so that all vaults are unlocked in the browser extension if they are already unlocked in the desktop client? Until now we have to unlock a vault twice: first in the desktop client and in the browser externsion...

Btw great work! Version 2.x is amazing!
