feat(Storage): Create a feature to sync folders and files from Storage to Local Disk

[lgmarchi]

File Sync Functionality

• Should allow us to choose a folder within uplink and have that folder replicated on the filesystem of the computer.

• Should allow changing of files within uplink, or within the folder now on the computer’s filesystem to automatically detect changes and be kept in sync. (I.e. if we delete a file in uplink it should be deleted from the computer and if we delete a file from the computer, it should be deleted from uplink.)

• All child files and folders should be kept in sync if the root level folder is set to sync locally.

• You should be able to choose where to keep your uplink “sync” folder on your computer.

• You should be able to share a folder that will be kept in sync with the recipients computer but they should not be allowed to make changes to the files and only read them. (If they have only read only-permissions)

• You should be able to share a folder with another user and any modifications either end does to the folder should be kept in sync. (If they have read-write permissions).

• Uplink should have some kind of watcher on the folder in question to automatically keep things in sync.
