utils.findPlugins() checks for the existence of an __init__.py which
results in an attempt to enable a plugin without an __init__.py being
blocked with the only notification being a message in the Plugins log:
WARNING Plugin "<name>" is not compatible with this version of QGIS.
It will be disabled.
This is not very informative, especially because it is the same message
used for a metadata version mismatch.
Adding this check to Plugins.getInstalledPlugin(), which already
duplicates the metadata checks from utils.findPlugins(), results in the
plugin being marked as broken in the Plugins dialog.
Fixes#19721
Virtual layers incorrectly show no feature when the expression filter string is empty, instead of correctly showing all the features.
Subset string needs to be tested against Empty instead of Null in order to correctly populate the wheres list and prepare a well formed SQL query string.
there is 2 icons in notifications, one from the app itself and one set from the notification
the icon application seems not to be set correctly on mac for now
only the windon icon is set in main.cpp with myApp.setWindowIcon
the icon defined in application plist does not seem to be correctly set
...so in this PR we set the notification icon to be the QGIS one, so it looks nicer
…ecial field/layer names
Fixes#19636
"Filter on joined fields" does not work properly in the following two circumstances:
- when the (original) layer is a "spatial layer": the virtual layer created is an attribute only / non-spatial layer, instead of a spatial one
- when at least a field name or a layer name starts with a digit or contains white spaces (or probably also other special characters): the virtual layer is not created at all (actually is created and instantly deleted) without warning the user
This fixes both and also updates the related tests accordingly and adds another test.* Enclose field/layer names in double quotes.

Three new easter eggs:
world : Add a world map to your canvas - it is the same world map as used by the CRS chooser
contributors : Adds the contributors json (used to be in docs, now moved to resources/data)to the map canvas so you can quickly see the locations of QGIS developers in QGIS
hackfests : Adds qgis_hackfests.json (in resources/data) to the canvas so you can quickly see the locations of all historical QGIS hackfests. Note the attribute table has other interesting data too.
