These allow plugins to extend the "Open Project" dialog by adding in support
for new file filters, which appear in the formats drop down list alongside
the existing "QGS Projects" entry.
Custom project open handlers then get first chance at loading project files.
This allows plugins to extend QGIS support by adding integrated support for
opening projects from non QGS/QGZ formats, e.g. allowing users to open
ArcGIS MXD documents or MapInfo WOR Workspaces direct from the project open
dialog.
These non-native projects are also added to the recent projects list and
welcome screen, giving them a truly first-class experience within QGIS.

"development/debugging" tools
These tools appear in a new Development/Debugging Tools dock,
and provide a unified handling and place for these tools in the
UI.
The intention here is that specialised development/debugging tools
will be moved to this common interface, e.g.
- network logger
- first aid style Python local variables inspector
- startup time debugging tools
- layer load and rendering time debugging tools
... ?
Returns a reference to the main window "Plugin Help" sub-menu.
Plugins are encouraged to insert help and about actions in this submenu instead of creating
a submenu under the pluginMenu() which solely contains Plugin Help or About actions.
For example, a plugin which only implements a processing provider should not
create additional ui menus just to link to the plugin help pages. Rather, they
should use this new submenu (available under the Help menu) to insert
their help links.
For the c++ api dox this expands to "\c nullptr" (the
\c directive indicates a code literal value), and for sipify/Python
it expands to ``None`` (`` is sphinx annotation for literal values)
Makes for nicer dox for both c++ and Python!
layout designer interface API
This commit adds more methods to the public, stable API for the layout
designer dialog, allowing plugins and scripts greater flexibility
in extending and hooking into the layout designer.
New API includes:
- access to the main menus shown in the dialog, allowing custom actions
to be added to the dialog
- access to the dialog's toolbars
- methods for adding (and removing) additional dock widgets to the designer
- the method used to show/hide rulers in the designer
otherwise if you access the config of the filter (or change app settings) from outside the main application settings dialog, results are not invalidate
for instance, if you update a URL of a service, results won't be updated
