Basic documentation of the 'ram' mode in the 'file' module
Move ram option from mode() type into open/2 spec

The mode() type is used in path_open and copy, two functions that
do _not_ accept the ram option (or is at least not supposed to),
why I moved the option 'ram' from the type down to the spec for
open itself. That also makes the option visible directly under open/2
in the documentation.
