fix: installation without sudo

[vmx]

I think it's good practice that users don't need to run sudo
to install something just to try it out. With this change, the
local bin directory is tried first, which usually is also in the
PATH. This way the installation script can be run without
sudo and should still work.

Can we put this at the end of the list so that it's backwards compatible? (i.e. if you run w/ sudo it will continue to put the bin in the same place)

Suggested change

	binpaths="$HOME/.local/bin /usr/local/bin /usr/bin"
	binpaths="/usr/local/bin /usr/bin $HOME/.local/bin"

Also will this work if $HOME has a space in it?
