Remove production file

Confusing to have this in here and can cause accidents.
Remove it since it should be generated by grunt.
Add task cards to browse view

This is a REALLY basic view of tasks and their tags.
The framework is in place for this to be a LOT cooler,
but I'm really blocked by the task-new stuff (like setting
locations, sponsoring offices, the need for task tags
to be in tag.js, and the renaming of tag types to be things
like task-people-required).

Also implemented popover clicks, so you can now click on
anything that has a popover and go to that person's profile.

If you're not logged in, you get a blank page.  This will be
fixed once the login system is moved to a backbone app instead
of a server side view.
Attachments implementation

Basic working implementation of attachments.

Can click 'add file', add a file, and it shows up
in the list.  Can delete the file if you own the project
or task, or if you were the one that uploaded the attachment.

Renders each attachment row and an 'empty' row.

There's probably much better styling that could be done,
but I'll leave that to the designers.
Attachment cleanup + fns

Add the time the attachment was created to the list.
Sort the list by the time created (descending).

Add new attachments to the top of the list, not the
bottom.

Add the person who created the attachment.

Fix up some styling.
Implement attachments basic functionality.

Merge branch 'sprint8-feature-attachments' into sprint8
Update build system

Modify CSS to be compiled for the project for production,
minimizing the number of files transferred and minimizing
the size of the resulting css.

Update grunt to build correct all of the targets.  You
now build the production environment files with:

	grunt build

Modify the sails lift --prod grunt rules to only
copy the necessary files (and hopefully speed up the
process of sails lift in production, especially on EC2)

	sails lift --prod

Remove all production references.
