Slightly nicer gitignore
Fixed old configuration settings

- in my .zshrc, replace absolute paths by $ZSH variable
- fix OS detection in Linux version of 'open' alias
  Whaddaya know, `uname -s` returns "Linux", not GNU/Linux.
  That's `uname -o`, but -o is unsupported under OSX among other OS's
Update License to reflect (ongoing) merge
VIM configuration based on tpope/vim-pathogen

- Uses vim-pathogen to handle vim bundle management for plugins
- plugins included as submodules, to keep in sync w/ upstream
- includes very rudimentary .vimrc based on tpope's
- backup/tmp subdirs to avoid folder cruft, .gitignore keeps repo clean
- line numbers & ruler enabled by default
- project-wide .gitignore updated to ignore VIM's .netrwhist
