Prettify message view in held messages

This replaces and is inspired by the work done by @maxking in !9 

The added benefits of this merge request:
* use only one modal (no transitions when displaying full message)
* it also drastically decreases the website's size since it is only using one modal for all messages, relying on javascript to display the correct information
