samba36: Remove legacy options

samba36: Remove legacy options

Browseable is now set through LuCI per share, so remove it. Same with
writeable (inverted synonym for read only). domain master and preferred
master seem to be legacy settings for Windows 9x. encrypt passwords
defaults to yes. Probably should not be disabled either.

Also reordered alphabetically.
