- et2-tree-dropdown requires options with attributes id AND value, text AND label :(
- fixing it really to use only one or the other is hard, as lots of mail app.js code requires tree to use id, but all select wants value
- Etemplate\Widget\Select::fix_encoded_options() now uses a special handling for real (non-associative) arrays adding value attribute from id
- client-side et2-tree-dropdown now searches child-options in children and item attribute, and checks both label and text attributes
