@alias should not override name and longname

[onury]

Documentation

/**
 *  ...
 *  @alias lib.secondaryName
 *  @memberof lib
 */
function originalName() { .. }

outputs:

{
    "code": {
        "name": "lib.originalName", // original name is only documented here
        ...
    },
    "alias": "lib.secondaryName", // alias
    "name": "secondaryName", // alias
    "longname": "lib.secondaryName", // alias
    ...
}

This is misleading. Since aliases are secondary names, the name and longname of the symbol should be kept unchanged. We already have the alias documented.

The whole point of the @alias tag is to treat the symbol as though it had a different longname. See the docs for this tag. Sorry, but we can't change this tag's behavior without breaking a lot of people.
