Display move source and responses on game page

Moved code to call and display move source and move responses to
functions.php. Added calls to display source and responses on the game
archive page.
Moved the game description to the sidebar under the make a move button
created working link back to game on the single move page
Link to respond to move on single move pages

* Made function to provide link to the make a move page.
* Refactored code on game archive page to use this function
* Added button on single move page to allow for response to move
* directly from the move page itself.
added link to login in header - redirects to current page
Added role functionality

* Added role creation page
* Added helper function to check if user has a role in a game
* Added conditional on game page to display create a role button if the
* user does not have a role and make a move button if the user does.
function to check if user has role returns role instead of true now. This will allow us to pull info from it later
added custom loop to show the role of the author of any given move - currently not working
changed background to red to test out heroku push
Changed background of body to blue.
Changed body text to yellow because I'm mean.
fixed display of role with each move through adding post type to argument array and reseting post data after the nested loop
fixed minor spacing issues
adds link to the role name associated with each move that goes to the single post default template to show the role name and role description
merges feature/roles into develop
fixed colors we experimented with during heroku setup
created the author template page and began to fill with some basic content, including a custom query that returns a list of the roles associated with the author. The next step here might be to provide the name of the game that role is associated with as well as a link to that game. Further step would be to return the most moves associated with each role
added a link to the author's page in order to have an easy way to access that page. Will remove at a later point.
now shows linked game title associated with the role
fixed colors from learning heroku deployment
