Release Candidate for Testing

A Release Candidate for testing. V2.1 will be totally usable (even though some features may be missing)

42-hours of Debbugin later

Added restore Locig and fixxed several bugs.
Full/Incremental and differential Backups/restores are now possible.

Initial Draft

Automatic and Manual Backup is possible.
Incremental Differential works too currently, but there is no restore yet.
(The restore also WON'T work with Files backed up now)
We'll work on this Issue to bring this feature ASAP.

This Release is in the State of PR #38
