This adds:
- API call to QgsMapCanvas to flash a set of features
- A right click menu option in the attribute table to flash
the clicked feature
- An option in the Search by Form dialog to flash matching
features
When triggered, the features flash allowing easy identification
without having to alter the current selection or map extent
This commit adds a new mode to the attribute table dialog for searching
and filtering features. When activated (using a button on the toolbar
or by pressng CTRL+F), the dialog will switch to form view and all
widgets are replaced with their search widget wrapper variant.
Alongside each widget is a tool button with options for controlling
the search/filter behaviour for that field, eg "equal to", "not equal
to", "is null", "greater than", etc.., with the options presented
matching themselves to the corresponding field and widget type.
New buttons appear at the bottom of the form for either selecting
matching features (with options for add to selection/remove from
selection/select within current selection) or filtering features
in the table (with options for adding features to a current filter
or further restricting a current filter).

This change allows the attributes of multiple features to be edited
simultaneously. It is enabled when the attribute table dialog is in
"form mode", via a new "multi edit" button on the toolbar.
In this mode, attribute value changes will apply to all selected
features. New widgets appear next to each editor widget allowing for
display of the current multi-edit state and for rolling back changes
on a field-by-field basis.
Changes are made as a single edit command, so pressing undo will
rollback the attribute changes for all selected features at once.
Multiedit mode is only available for auto generated and drag and
drop forms - it is not supported by custom ui forms.
