RELEASE: 3.23.05.30

Improving productivity, layout, performance and administration.

Productivity:
* Coding fragments
  - visual cues for selected fragment
  - suggestions of already created codes
  - fragment groundings can be removed
* Hints and tips for tables and graphs
* Reverting a memo to a previous version
* Creating cohorts of users
* Orienting and situating connections between dimensions

Layout:
* Explicit `confirm`/`save` and `cancel` buttons (in addition to implicit the `return` validation)
* Improved responsive design, with icons and tooltips

Performance:
Optimized design for faster loading, even under heavy usage:
* Function scripts mutualized in static js files
* Multiple design documents
* Incremental/lazy loading indicated by spinners

Installation and administration:
The installation and administration now take advantages from Docker, AAAforREST and CouchDB updates:
* Docker facilitates installation procedure and allows to choose the amount of server memory to allocate
* AAAforREST 2 provides detailed logs
* CouchDB 3 includes automatic compaction/clean up features

Admin also can henceforth easily customize:
* navbars color
* sponsors (for LDAP/local users)
* duration in maintenance messages
