Consider allowing method parameter links

[abgruszecki]

See #149 (comment):

If it isn't available already ... it would be nice to reference a function parameter in the documentation text (such that it is seen as a function parameter and picked up during refactoring and such)

/**
 * Adds one to the specified ???
 *
 * @param number given number to add 1 to
 * @return ??? incremented by 1
 **/
def addOne(number: Int): Int = ...

A way to specify number, say [[@param number]] or something like that.
