skidder 1c394c6d4b Fix up server-side database aliases
- expand Windows SS local connection strings on the client side unless they
specify database aliases (return to backward-compatible behavior)
- use aliases for database creation
- do security checks after database file name expansion
- forbid usage of relative paths in aliases
- do not stick to 8.3 filenames on Windows as it causes problems
