Reset file attribute information after usage

TorBrowser bundle leak "local" information on when it was last used .

This is because the local filesystem keep MAC (modified, access, creation) time.

It means that from a forensic analyst perspective it will be always possible to identify which is the last time the TorBrowser has been started (and probably when it has been closed) by carefully looking at the "atime" attribute of the filesystem in the directory where TBB is stored.

To fix this issue the TBB, on start and on close, should reset the "atime attribute" of all the files and directory where it is stored.

This can be done on all major filesystem with proper programming API (FAT32, NTFS, HFS, Ext4, etc) .

To upload designs, you'll need to enable LFS and have admin enable hashed storage. More information
