[Kimchi-devel] [PATCH][Wok] Change plugins get_list to return only loaded plugins

[Rodrigo Trujillo]

When using multiple plugins, it is possible that some plugin has a
problem and is not loaded (like when there is a missing module).
In this cases, Wok is not going to load the plugin in cherrypy
configuration, but plugins API return the missing plugin name.
When this occours, UI becomes broken and it is not possible to use any
other plugin, because Wok UI is blank.
This patch fix this problem, returning only plugins names that were
loaded by Wok.
