### None of the following *need* to be used, feel free to override

### plugin before or after you've done etra things that you need to.
### in order for them to work, you need to have setup
# self.TranslationContext
# self.PluginTextShort # eg "Image" for the image plugin
# self.ConfigSection - where the items in the media manager are stored
# this could potentially be self.PluginTextShort.lower()
#
# self.OnNewPrompt=u'Select Image(s)'

# assumes that the new action is to load a file. If not, override onnew
# self.ListViewWithDnD_class - there is a base list class with DnD assigned to it (openlp.core.lib.BaseListWithDnD())
# each plugin needs to inherit a class from this and pass that *class* (not an instance) to here
# via the ListViewWithDnD_class member
# The assumption is that given that at least two plugins are of the form
# "text with an icon" then all this will help
# even for plugins of another sort, the setup of the right-click menu, common toolbar
# will help to keep things consistent and ease the creation of new plugins
# also a set of completely consistent action anesm then exist
