Additions

I've added a few things and moved the aliases to their own file. See commits for description.

One thing I omitted - but you probably want to look into is the Sublime Text `subl` command (``/Applications/Sublime Text.app/Contents/SharedSupport/bin/subl``).  It exists for among other things, to launch Sublime from CLI.

I just symlink the subl into /usr/bin/ and then have a generic:
```
alias txtedit="open -a subl"
``` 

Also this way if user decides they like textwrangler better they can do:
```
alias txtedit="open -a /Applications/TextWrangler.app"
```
