For book, shelves and chapters.
Made much of the existing handling generic to entity types.
Added new MixedEntityListLoader to help load lists somewhat efficiently.
Only manually tested so far.
Rolled out HTML editor field and store logic across all target entity
types. Cleaned up WYSIWYG input logic and design.
Cleaned up some injected classes while there.
Added since we can't always be sure of future image usage, and in many
cases we don't generate ahead-of-time.
Also:
- Simplified image handling on certain models.
- Updated various string handling operations to use newer functions.
Both caught in tests:
Fixed loss of permissions for admin users when entity restrictions were
active, since there are no entity-restrictions for the admin role but
we'd force generate them in joint permissions, which would be queried.
Fixed new role permission checks when permissions given with only the
action (eg. 'view'), since the type prefix would be required for role
permission checks. Was previously not needed as only the simpler form
was used in the jointpermissions after merge & calculation.
This adds parsing of page content so that headers apply a boost to
scores in the search term index.
Additionally, this merges title and content terms to reduce the amount
of stored terms a little.
Includes testing to cover.
Removed some common functions from other entities.
Aligned implementation of getUrl()
Cleaned phpdocs and added typehinting.
Also extracted sibling search logic out of controller.
Tools seems to fit better since the classes were a bit of a mixed bunch
and did not always manage.
Also simplified the structure of the SlugGenerator class.
Also focused EntityContext on shelves and simplified to use session
helper.
