[New Feature] Auto show strings values if the mouse is hovering in the strings key.

[alexlee002]

**Feature 1**: If the mouse is hovering in the strings key, popup a table that shows all the values of this strings key.

**Feature 2**: if I cmd+click the strings key, jump to the strings file automatically

**Feature 3**: show all the existing strings table name in auto-completion window.

Thank you for your ideas. From my experience, I think Xcode plug-in must be small, and we must be careful about adding new features.

For example, the previous version of Lin (for Xcode 4 and 5) had a popup which shows all key-value pairs, and the users can add a new pair from it. But it made Lin complicated and it was hard to maintain. And its popup conflicted with other Xcode plug-ins (like HOStringSense). That's why I totally remade Lin, and built it in Xcode's autocomplete mechanism, and removed extra features.

So about your ideas, Feature 1 is not good, Feature 2 is good, and I don't understand why Feature 3 is necessary.
