Changed Samba Configuration (#212)

- New directories and files have owner Pi (No need for chmod 777)
- First user name: USER
- 2. 3. ... user name: USER2, USER3
- First share name: SHARE
- 2. 3. ... share name: SHARE2, SHARE3

See: https://github.com/dperson/samba
NOTE3: optionally supports additional variables starting with the same name, IE SHARE also will work for SHARE2, SHARE3... SHAREx, etc.

Not sure if PERMISSIONS are needed
