+ wd.aliasingClaims: copies wikidata Properties array to
used Properties to extend the chance to find results
fixing the missing icon declaration, required since the
last {{icon 'name'}} handlebars helper refactoring
showAllLocalFilteredItems waitsForData
removing the icon alt to avoid overlapsing text at every load
+ personal and contacts items to WikidataEntity view
- adding notes and entity to Item matchable attributes
+ Items::byEntityUri
+ wd.normalizeTime
+ author_li displays birth and death dates when available
- simpler Entities collections traversal
+ Entities.length map-reduce
trying to fix the endless loading and missing alert-box
on entities search fail with a temporary on404 method
- writing down the concerns on the _.log method
- more tolerant logXhrErr method
updating WikidataEntity @status after first formatting
slighty cleaner book_li
shared-lib get rid of global variables as now required by server-side
- re-implementing the 'filter:inventory:owner' command
  for Items.contacts.filtered to allow contact_li to filter inventory
- allowing a temporary solution for user items from the same entity
  -> showing the first of them and console.warn'ing
"stashing" the global preventDefault policy:
  - internal links with href were sometimes reloading the page
  dispite being catched
  -> commenting-out every internal href to move forward
  - replacing the old filters by an extarct of Backbone.Intercept
  filter technics, even if useless now that all href were neutralized
- _.toSet becomes _.uniq to mimic lodash naming
- _.uniq move from shared to local utils as server-side gets lodash
(not using lodash on the client-side, as it seems to be way
heavier than underscore)
testing level-browser
rm unused layout
Initialize:
- introducing LocalCache constructor to handle relations
  between module data and levelup/indexeddb
- initializing data_state handler before modules
  so that modules can't request() its reqres before
  they are defined

Local Dbs:
- bundling LevelDB libraries into window.Level

LocalCache:
- get data in LevelDB first
then complete with remote data
then cache remote data in LevelDb
finally return all the requested data
- /!\ doesn't handle data freshness yet

Data Sate:
+ waitForUserData reqres
- starting to implement new strucutre of contacts: relations
divided between friends, userRequests, othersRequests
- using the LocalCache constructor (see prev. commit 842648d) to
cache friends pubic data

+ _.values (adapted from lodash implementation)
(muted logs update)
