I updated the bash_config file. As well, I updated the description of
dotfiles in README.md in order to reflect the new code that handles
differences between OS X and Linux.

A necessary .gitignore file was added.

Finally, I removed a file that is now in the .gitignore file.

	new file:   .gitignore
	modified:   README.md
	modified:   bash_config
	deleted:    vim/.netrwhist
