Implement phasing

[peterholmberg]

With the addition of T6/S3 weapons the results view is starting to get less relevant for players that are still in the prebis, t4 and even (to some extent) T5.

If I am running Karazhan on an alt and want to know what rings to get I am fed with results from late T5 or T6 which may not be relevant for this character. As such, adding a phase property to items and a checkbox in the interface would present more relevant results for those users.

Good suggestion!
