Working on more emacs configuration

Added magit and projectile to the default packages. Magit for nicely
working with git repositories while inside emacs. Projectile for working
on project directories while within emacs.

Also added some comments and basic configuration changes to the init
file.

Finally added a fix mentioned on the melpa site to resolve an emacs 24
issue related to resolving package dependencies.
