Hello,

- In textaddons autogenerate lib, don't allow to collapse with double click in textautogeneratehistorylistview
- Reduce duplicate FlowLayout class 
- Fix attachment widget layout (Use QToolButton). This class is used in kaichat.
- Fix initialise variable in plugincommonmodelinstalledinfosdelegate
- Reduce duplicate code in plugin textaddons autogenerate
