Simplify bashrc, modify install.sh, add nvim/

bashrc is now simpler.  Hopefully with the same functionality.  Remove
some of the default stuff that came with Debian years ago.  Start with
default Archlinux bashrc as base (very minimal).

install.sh now recommends only using slinks.  nvim and zathura now get
linked directory-wise.  This is way better because added configuration
files will get here seamlessly.  Doing diffs between 2 independent
copies is painful.

Now I'm transitioning to NeoVim.  I've copied all relevant config from
vimrc (Vim) to init.vim (NeoVim).  Very promising.  File got smaller and
more organized in my opinion.

PD: Cheers, this pulse15 laptop is amazing.
