added navbar menu entry and added swp files to gitignore file
Corrected js file path. Added menu options to navbar.
Modified models.py to support image upload. forms.py is now using a custom filter for post.blog_post_image that will provide only the last value of the path. created a custom function called split_string.py. View was change to be able to check/save image files. Some image files were added for testing purposes, might be deleted if considered unnecesary. Moved a bit settings.py mostly variable line. Added options to Navbar menu. Last but not least, added a custom url to server media files as this is not supported out-of-the-box by Django
