Add missing newlines at EOF. Remove redundant comment. Fix grammar in comment.

Add helper aliases for show/hide files. Add helper alias to recursively delete
.DS_Store files.

Add helper function to open node api in browser. Add binaries installed via
npm to path. Tell node where to find things (what things?).

Add helper function to restart an app running on Pow!

Merge completion with official brew completion. Add a helper to link official
completion into oh-my-zsh plugin (without overwriting). Add an alias to list
installed brews. Add brews to the path (in a somewhat strange way).

Add helper function to list gems in a pretty way (only with rvm, for now). Add
missng EOF newline and a todo to the ruby plugin.

Add helper function to get rvm head. Add helper function to link zsh
completion that comes with rvm into om-my-zsh plugin directory, but don't
overwrite the completion that comes with oh-my-zsh (oh-my-zsh's completion is
better, but I want to be able to compare).

Add alias to list installed rubies. Add alias to list gemsets in active ruby.

Add helper functions to switch gemsets on ruby-1.8.7-p334 and ruby-1.9.2-p180.
Add completion definitions for helper functions.

I've changed it to use `view` instead of `vim -R` to make it hopefully
more editor-agnostic.

In detail:
gup - now completes with remotes like git fetch would
gdv - got git diff completions
gc/gca - now zsh will suggest files in staging area
gba - suggestions as for git branch
