straightening out the text on the map buttons
fixing issue in which the bookmarks were not resolving correctly
updating bookmarks to fix some bugs noticed in marco
adding settings for min and max zoom as well as center point and initial zoom
actually forgot a bunch of files on that last commit...For this commit I moved the settings model into a new mp_settings app and have, hopefully this time, included all the necessary files related to the center, zoom, and project name and logo settings...requires migrating mp_settings app and specialization can be specified via the django admin
enabling configuration for map links, including bitly registration data, and logo appearance on embedded map
ensuring mp settings allows for differentiation between map links button (linking to home page) and map links project title.  adding popover for esri ocean basemap attribution.  ensuring short url checkbox is not offered when no bitly registration fields are populated (in the case of active mp settings record or no active mp settings records).  changing default mp location to the pacific northwest. shrinking the window size of the iframe example to better match the sample iframe.  ensuring state handles the showing/hiding of the logo (for embedded maps).
