+ entity actions buttons with dropdown for transaction-type options
- removing wikipedia-preview-related code
renaming wikidata_entity entity_show as it is also used
by isbn-based entity
cleaning _.inspect
(remove inspect after using as it keeps reference of the inspected
object making the garbage collection impossible)
MAJOR reorganization: dispatching in modules folders as much
as possible
fixing paths broke by previous commit major reorganization
+ making handlepars partial helper accept shortened paths
  (e.g. module:subfolder:file ), while defaulting on
  the 'modules/general/views/' folder
finishing to replace href attributes by data-href
data-href are sort of a commenting-out thing as they
have no use. Waiting to find a way to keep the href
while not triggered a full reload of the page
_.error accept both string error message and Error object
=> creating an Error object to get a stacktrace, if none is provided
+ slim_package script: to cut down package.json length ending in vendor.js
due to un-optimized browserify process
- renamed scripts
+ items_columns view with child: item_figure
- welcome view move from Foundation grid to flexbox
+ .shadowBox (with dedicated scss file)
- general scss file get imported from general module
- users and entities modules initialize sooner:
  as welcome view needs
  - to fetch items entities
  - to use users helpers for username and picture
handling anormal cases
Items List:
 - items_list new default childView: from item_li to item_figure
 - rm item_li, methods go to item_figure

Inventory tools:
+ working toggleLayout

General scss:
+ vendor-prefix mixing
+ flex classes to extend from
allowing to instanciate ItemsList with the columns option
- DRYing by extending from flex classes
- fixing the top margin issue
plus details
glowing jk-focus'ed element
+ icons
+ Backbone.Collection::attributes
- making users subcollections add method accept data collections
+ users.subCollectionsStats helper
