This module lets you take the input from a field and allows using HTML and token replacement (or alternately PHP) for display.

"File entity provides interfaces for managing files. It also extends the core file entity, allowing files to be fieldable, grouped into types, viewed (using display modes) and formatted using field formatters. File entity integrates with a number of modules, exposing files to Views, Entity API, Token and more."

I just read a great article on this that breaks things down very well. You can find the original article here: http://fredparke.com/blog/create-your-own-tokens-drupal-7

Basically, you need to use two hooks. The first one tells the system about your token. The second one contains the specific logic for your token.

The File Aliases module allows you to use token customizable aliases for your uploaded files, giving you the ability to keep your file system organized as per usual while providing clean looking paths (i.e., no more '/sites/default/files/').

Adds a link field

Otherwise known as ECK, Entity Construction Kit allows the creation and management of new fieldable entities in a UI.

Mediaelement.js is a cross-platform HTML5 / Javascript / CSS video embedding method which has Flash and Silverlight fallback. It is included in Wordpress, from what I hear. It has been in devlopment for quite a while. The documentation could be a little better though and it's hard to find a good tutorial on using the API. Here's the basic steps:

It's been awhile since I've used it. It provides a location field. From what I remember, it's a little buggy. Quote from Mediacurrent, "Address Field - I used to use the Location module fairly often and in early Drupal 7 I used this module. I tend to like the Geofield module a lot more than these particular modules." http://www.mediacurrent.com/blog/top-drupal-7-modules-winter-2014-edition

The media module allows changing allowed file types that can be loaded when using fields but not at /file/add. So, here's how I got around that:
