0.4.0

New Features:

• Fully reworked the Wiki Content hierarchy, it is contained in a standalone resizable sidebar of the Wiki Details and Editions pages.
  It supports unlimited nesting of elements and drag & drop to reorganize them in arbitrary fashion.
  It has convenient visual aids now and and all the bugs or limitations regarding items rearrangement have been resolved.
  The project header and dropdown Wiki links now redirect by default to the (root) of the Wiki Content.
  The Wiki tree now also works on mobile, yet it uses explicit handles for reordering because of the touch and slide mechanics.
  Anyway, better try it than explain it further 😎
• Wiki Overview now shows an indented list to denote hierarchy.
  And also does the parent dropdown in the Wiki page Edit modal.
• Implemented purging of Wiki Editions (alongside the Restore functionality).
  Updating an Edition now checks for actual changes
  and if nothing meaningful has changed (title and content) skips creating the edition.
  Actions like changing the parent shouldn't trigger new editions to avoid unnecessary multiplication of the data.

Improvements:

• Massive improvements to UI/UX.
• Fixed titles of pages to match projects.
• Enhanced details and search on Wiki Index.
• Wiki pages content is now expandable on demand (instead of preloaded) for the Wiki Index and Editions.
• Multiple adjustments for styles, colors, positions and layouts of global containers and page elements.
• Adjusted layouts of elements in create/edit wiki modals, unified the modals themselves.
• All buttons now have tooltips (yet not translations).
• Massive cleanup of redundant and bloated code, misleading comment leftovers, unused method parameters, etc.
• Quite some refactoring on demand and on the go.
• Naming unification for styles, elements, methods, parameters.
• Reducing copy pasted and coupled code.
• Code syntax formatting and beatification for better readability.
• Improved this very ChangeLog, transforming it into MD.

Bug fixes:

• Fixed file viewer
• Fixed routes for all controller actions in use.
  They used to be copy pasted and were useless as they were all the same.
  Minimalistic possible and sensible notation is proposed.
• Fixed the bug that a wiki page could assign a parent from its own subtree,
  thus effectively and irreversibly breaking the wiki page hierarchy.
  Now the parent dropdown in the Edit modal shows only the possible parent nodes.
• Fixed the jquery-sortable.js library (which is not supported and maintained for quite a while),
  to work on mobile and to allow correct touch and drag & drop elements without sliding the whole page along.
• Obviously, all the functionality about managing wikipages' ordercolumn has been totally revamped to guarantee correct sequential numbers for subpages.
• Various small bugfixes.
