Add bash-it restart command

[NoahGorny]

This command will re exec the shell, yet cd to the prev pwd
I briefly floated the idea in #1665 (comment)
I still did not test this on Mac, and also I could not enable the --login option, as I wanted to run command after shell initialization. @ahmadassaf could you please test this and tell me if this works on Mac?

Just tried this on my MacBook, looks good to me:

Seems to work just fine.

Thats great! I think this is a great addition to the set of abilities bash it has.
I want to merge this, what do you say @nwinkler 😄

[nwinkler]

Agreed - this looks good! Thanks for adding this!

I'm wondering whether we want to include this in the documentation. I've checked the main README file, it currently does not provide a complete list of all commands (e.g. bash-it reload). We might want to add that at one point - probably as a separate PR when (hopefully at one point) rework the documentation.

Created a new issue, in the meantime, I think we can merge this (and then #1626)

[nwinkler]

Merged! Thanks again for the work you put into this!

I'll let you handle #1626...
