Modularity: Moved "create_links" from "helpers" to the "Link" class
Changed routes to create a "Link" and several of them to follow a REST-like pattern
Fixed the appearance of the pages for a single "Link" and "Tag"
Changed "Settings" style and added more Glyphicons
Added Radio button to the "Settings" page
Improved the appearance of Links
Improved the appearance of Links and Tags
Made some elements on "Link" only appear when hovered - CSS magic!
Generalized the hover-over-show-stuff thingy
Made an AJAX request when clicking on the "Delete" button. It _works_! Also, added cute spinner showing progress
Generalized the AJAX-deleting functionality to both "Links", "Tags" and anything else
Created "Setting" module for configuring in-app stuff
Made the "Setting" module interact with a YAML settings file
Made AJAX requests to automatically refresh the application "Setting" - AWESOME
Added a cute progress bar - thanks a lot NProgress!
