Fix syntax errors, move order of upgrade checks, enhance folder check, fix shortcuts

Fixes a syntax error with the NoServiceUninstall section. Moves the detection of an existing Service and datadir further up, so it happens before we decide how the installation will happen. Removed a newline from a comment, and enhanced the existing directory check. Adds an existing folder check, as well as a prompt if the user wants to continue with it or not. Also adds the datadir property to shortcuts.
