Install latest Zsh+Zim

[rajat2004]

Closes #59 https://github.com/zimfw/zimfw

TODO:

• [x] Actually test if this is working :sweat_smile: (Probably in VirtualBox)
• [x] Install latest zsh for Ubuntu 16.04 (Newer Zim requires Zsh >= 5.2)
• [x] Update instructions for multiple users

Works on Ubuntu 18.04

Update instructions for multiple users: probably just need to add

sudo cp ~/.zshenv /home/$NEW_USER/.zshenv

to the code block

Great, thanks for testing!

What about the .zimrc, .zshrc etc? Those would also need to be updated right? I haven't installed and checked this myself yet but, the templates are not there in the repo anymore, they're in the script itself, so I think those will also need to be copied from the orignal user's directory itself

@rsnk96 Ah hell! I force-pushed the branch without fetching your commit for updating the Readme for the multiple users. If possible, could you add back your commit now, sorry for this!

So the main points left to decide on-

1. For source built zsh, should we stick to a specific version or the latest tag? (Only on Ubuntu 16.04, on 18.04, apt install)
2. Disable zimfw from updating or not?

IMO latest tag should be good enough for source built, and disabling zimfw from checking updates doesn't seem to be a good thing, the user can decide whether or not to do it, though I don't have a strong preference for any choice

I'm okay with both 👍
