Document inversedBy and mappedBy attributes on mapping annotations in annotation reference

Regarding http://www.doctrine-project.org/documentation/manual/2_0/en/annotations-reference

The association mapping attributes should show mappedBy and inversedBy as optional attributes and describe their use on the owning vs. inverse side. As of today, only @ManyToMany shows mappedBy as an attribute, and inversedBy is not mentioned at all.

Each of @OneToOne, @ManyToOne, @OneToMany, @ManyToMany need to be reviewed to be consistent with association mapping documentation at http://www.doctrine-project.org/documentation/manual/2_0/en/association-mapping
