Change Campaign Slug Base

/**

 * By default, campaigns are located at yoursite.com/campaigns/campaign-name. 

 * 

 * If you want to change the /campaigns/ bit to something else, you 

 * can modify the campaign post type definition using the example below.

 *

 * In this example, we change it to /projects/. The URL structure then becomes: 

 *

 * yoursite.com/projects/campaign-name

 *

 * IMPORTANT: After adding this snippet, go to Settings > Permalinks and click update. The 

 * change will not take effect until you have done this. 

 *

 * IMPORTANT, PART 2: When you change your site's URL structure, WordPress does not 

 * perform any automatic redirects for you. So if you have external links pointed to 

 * yoursite.com/campaigns/campaign-name, these will not automatically be redirected 

 * to yoursite.com/projects/campaign-name
