basic course model setup :feelsgood:

I'm trying to do smaller commits, more atomic. Still this has
changed some other things: added a seed and removed comments in the
html
front end form for creating a course

it still has no interaction with backend, just created the route,
the controller and the template. I also changed user=>member and the
default route in the router is '/signin' not '/signup', but I will
change it to 404 I think.
member-course n-n relationship working :metal:

Gave up on has_and_belongs_to_many and instead using an intermediate
model. Tweaked the styles a bit as well :)
some style changes

Commit with the style changes to avoid polluting a commit that
should be about something else.
course list and form working! :godmode:

It turns out that `type` is a reserved word (which should've been
obvious but whatever), so I changed type to course_type, besides
that the rest is pretty straight forward. New template, new
controller and actions. The front end side is starting to become
a monster, when I have something working I should pause and
restructure the whole app.
ninja! :shipit:
