Update install, rm dotfilesLink, mod colors.

Add:
	sshconfig
		-add entry for tourdecity application.

Rem:
	shell_scripts/dotfilesLink.zsh
		-replaced by "/install.zsh"

	shell_scripts/termColorsFonts.zsh, zsh/prompt.zsh
		-format for color escape codes is specific to the zsh prompt, and thus
		termColorsFonts.zsh won't be realistically sourced (used) by other
		shell-scripts -- copy contents used by prompt.zsh into that file, and
		remove termColorsFonts.zsh.
