cosmetic changes to messages controller; having a medlging vhd feature; factoring out code for doctors to separate the behavior for regular doctor paging and handling medgle requests; adding code to the messages controller to support this reorganization; the schema is messed up because of migrating to sqlite3 for development, but hopefully it won't cause issues
adding medgle_on migration to projects
Merge branch 'medgle' into projects
