Adds skeleton of signin modal to the landing page.
- can click signin link and modal appears
- can click close (in modal) and modal disappears
Adds AJAX to render login form inside of modal.  Can sign in via modal.
Disables scroll while modal is open.
Fixes bug with rendering signin modal **2 times (sessions#new set to layout: false)
Implements redirect to index with flash message (on modal) if login fail, else signs a user in.  Also modifies user model to make student_id readable (otherwise successful login results in error being thrown).
Changes logout (sessions_controller#destroy) to render root_path instead of login_path
Adds text-shadow to sign in and sign up buttons.
Adds modal for signup.
Cannot create new user, but issue appears unrelated to implentation of modal as the issue occurs with the direct users#new user#create paths, and in rails console.
Removes unnecessary module from landing.js
Fixes error with user creation and login (thanks Eli), removes dead code from UsersController#create (else branch).
fixes merge conflicts
Fixes bug with dashboard displaying all Contacts (students); now shows only current user's contacts/students.
Removes binding.pry from DashboardController#index
All login integration specs now passing, modified gemfile to use ruby 1.9.3 because I don't have 2.0.0 on this machine.
All specs pass, removed unnecessary (i.e. redundant) signup specs.
Ruby version changed back to 2.0.0 in Gemfile.
