Show icon on Post categories

[sseerrggii]

We want to show icons from glyphicons to identify post categories, the icons are:

Acompañamiento
glyphicon glyphicon-random

Asesoramiento
glyphicon glyphicon-briefcase

Clases
glyphicon glyphicon-education

Estética
glyphicon glyphicon-scissors

Ocio
glyphicon glyphicon-music

Otros
glyphicon glyphicon-asterisk

Préstamo de herramientas, material, libros, ...
glyphicon glyphicon-wrench

Salud
glyphicon glyphicon-apple

Tareas administrativas
glyphicon glyphicon-list-alt

Tareas domésticas
glyphicon glyphicon-shopping-cart

Te places to add it are before the name of category on:

• Post list
  
• Post detail
  
• Post search modal

@sseerrggii implemented in #663:

NOTE Since categories are editable, I added a fallback to the current icon 📁 in case the name is not found.
