UI tweaks part 1

[robby-d]

Some overdue minor UI tweaks:

• remove "my portfolio" and "top assets": These aren't used and don't work well anymore. Instead of fixing them, remove them from the UI for now. we may want to add them back later, or not.
• Remove the "more" button, and put Network Stats on the top bar instead of the left bar
• remove the "minus" icon on the top bar (which collapses/shows the side bar)??? or is there ever a case where this is useful (e.g. we already have an arrow button on the side bar itself)

anything else? @unsystemizer @rubensayshi @x-ETHeREAL-x

• Make it possible to easily copy wallet address to clipboard by clicking on it (either twice, or select+copy to clipboard). Currently when one clicks on wallet address that opens a modal on which one has to click the address again to copy it to clipboard
• Remove "Make divisible" check mark (the default) in asset issuance or remove the current advice? Currently we suggest to issue asset as divisible if unsure, but it seems lately undivisible tokens/assets have been more popular. Maybe some sort of advice/link should be placed there instead of that suggestion.

I'll have to poke around and check the forum and personal notes to see if there's more in which case I'd add it here.
