Let --sessionfile default to a more persistent path (#659)
The presence of a sessionfile avoids the usage of the failure-prone login mechanism. This commit addresses a suggestion in #615 to store the sessionfile in a persistent path rather than a path within a temporary directory if no --sessionfile parameter is given. The default path is now: $XDG_CONFIG_HOME/instaloader/session-USERNAME or ~/.config/instaloader/session-USERNAME on Unix, %LOCALAPPDATA%\Instaloader\session-USERNAME on Windows. If no file exists in the new path, Instaloader tries loading from the path where the sessionfile was stored before this commit, hence it automatically migrates to the new sessionfile path.
