#3493: Wrong BView scripting properties resolution

--------------------------------+-------------------------------------------
 BView and BControl expose pairs of scriptable properties with the same
 name. For instance, there is one 'Frame' property that responds to
 B_GET_PROPERTY command and one 'Frame' property that responds to
 B_SET_PROPERTY command.

 This is incorrect because it makes specifiers non-unique and does not
 follow the BeBook specification. It may break applications that rely on
 specifiers being unique and containing a _list_ of commands.

 EXPECTED BEHAVIOR

 The correct way is to have one property that includes a list of all
 supported commands. Likewise, the description should be changed to explain
 that a property can be _both_ read and set. Like so:
 { "Frame", { B_GET_PROPERTY, B_SET_PROPERTY, 0 },
 { B_DIRECT_SPECIFIER, 0 }, "Gets or sets the view's frame rectangle.",0 },

 STEPS TO REPRODUCE

 Issue a B_GET_SUITES scripting command to a BView instance, observe the
 duplicates in the reply.
