Mostly cleaning up to easier build backend. Moved classes and plugins to a "lib" folder. They can be used from both frontend and backend. Moved backend to backendfolder. Renamed its index.php to feed.php.
Changed all references in codes so it SHOULD be working even though lots of paths have moved.
added bootstrap framework to build the backend-admin upon it.
added a conf folder for the config file and if we need more

make issues if something is not working correctly.

KNOW BUG: instagram-plugin really really wants to know credentials. without it in settings it can bug out. will fix.
