This commit does a couple of things:
- It changes a label in the wallet menu from "Add/remove Token" to "Manage Assets"
as it has been designed
- It changes the asset list so a hover state could be introduced. Previously there
was no visual effect or response to mouse hover on asset items
- It improves usability of the asset list by making an entire asset item
clickable to toggle the asset in the wallet. This was not possible before.
Users had to click the checkbox achieve this effect
Closes#1631
