Summary: prevent recursive loading of gui-plugins

Initial Comment:
if a gui-plugin loads other plugin, we might easily encounter a recursion (where the plugin tries to load itself).
while the current gui-plugin loader mechanism tries to prevent re-loading of the "same" plugin (based on the filename of the plugin), it doesn't catch recursive loading.
the attached patch fixes this, by adding the to-be-loaded plugin to the "::loaded_plugins" list, then tries to load it and removes it from the list if the loading fails
(rather than adding the plugin to the list after the loading succeeded)
