Description of the problem being solved:

Simplify process of finding potential Watcher's eyes for your build.

Had a test of this PR and it worked as expected but there were some potential issues I ran into

• If you already have a Watcher's Eye in your build and you generate weights on a socket that does not currently contain the active Watchers Eye, it will not remove the original Watcher's Eye from the build before generating new weights and will also not generate a minimum weight value. People will probs make this mistake and have no idea that the weights are wrong
• With the Watcher's Eye search being hidden behind the jewel options I believe many people will not realise that it exists. I think it would be better to have it located below the Megalomaniac search in the main UI

We have a PoB dev Discord server that allows much easier communication, send me a friend request or message (LocalIdentity) and I'll send you an invite to the server
