Implemented mods can't access random from dashboard #88. Please note this doesn't use mod custom_pages functionality provided by vichan (because the that only works if your overboard has name that doesn't look like other boards), and requires ['overboards'] to be set as an array of board uri's which are overboards, with the correct values for type (theme type e.g. ukko, rand or semirand) title, subtitle, thread_limit and exclude in array of for each board uri
