feat: improve dialogs UX

[hacdias]

This:

1. Improves dialogs UX on all OSes.
2. Cleans up the code a bit and moves more strings to i18n.
3. Adds a dialog when the user tries to do some action that requires the daemon to be turned on (screenshot, add files, download hash) with the option to turn it on.
4. A nice read: https://medium.muz.li/ok-key-and-cancel-key-which-one-should-be-set-up-on-the-left-4780e86c16eb
5. Updates the signature of the getIpfsd function. By default, it assumes the code really needs the object so if it doesn't exist, the user will be asked to turn IPFS on. We can pass a true value as argument to make it optional.
