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.

+" NeoVim init.vim
+" 
+" Differences with good ol' Vim:
+"
+" NeoVim has so many of the modern and helpful Vim options on by default.  I'll
+" remove most of the old Vim configurations that now come by default in NeoVim.
+"
+" Also NeoVim uses XDG directories by default, keeping a clean directory tree.
+"
+" NeoVim also allows for this file to be written in Lua.  I'll stick to using
+" Vim script becuase it has more documentation and is more concise configuring
+" Vim options.
+"
+" Instead of viminfo, NeoVim uses shada files (SHared DAta) (different format).
+" See shada-file-name.
+"
+" For some reason, as of version v0.8.3 of NeoVim, Vim internal codes for shift-
+" and control- function keys change in NeoVim.  <S-F1> changes to <F13>, and
+" <C-F1> changes to <F25>. See https://github.com/neovim/neovim/issues/7384
+"
+" Plugins:  There are a lot of ways to install "plug-in"s in Vim.  My prefered
+" way is using Vim packages, available since Vim version 8.  See packages.
+" 
+" Tips:
+" * To show navigate help files:
+"       K       " while on an option to see it's documentation
+"       CTRL-]  " navigation while on a Vim help file
+" * To re-indent:
+"       tab->spaces     :set tabstop=n      :set expandtab  :retab
+"       spaces->tab     :set noexpandtab    :set tabstop={softtabstop}  :retab!
+" * To justify:
+"       To 'justify' comments or block of text (paragraph) use `gq{motion}` or
+"       `gp{motion}`, where {motion} can be `[/`, `]/`, `ip`, `i{`, `a{`.
+" * To see the last page of previous command:
+"       `g<`
+" * Buffer stuff:
+"       :ls         " shows all buffers
+"       :b N        " Go to buffer N (integer)
