support @memberof with namepaths including instance and inner members

[jfirebaugh]

Examples:

• @memberof Parent# (equivalent to @memberof Parent, @instance)
• @memberof Parent~ (equivalent to @memberof Parent, @inner)
• Nested paths such as @memberof Parent#Child

A worked example here:

/**
 * @class
 */
function Parent() {}
/**
 * @memberof Parent#
 */
function a() {}
/**
 * @memberof Parent~
 */
function b() {}
/**
 * @memberof Parent.
 */
function c() {}
