Let the users decide, whether they will use it in normal mode or portable mode.

In portable mode:

• saves all data from Roaming folder (Windows) in execute folder (where the *.exe or *.jar is located)
• maybe the auto unlocking feature Auto unlock vaults on program start #40 should not be available here

One solution could be the Portable Apps Platform App Maker, but a real portable mode of the application is much better
