The pigment plugin depends on the poblesec plugin

[Olivier Tilloy]

There is a direct circular dependency between the pigment and poblesec plugins.
The pigment plugin should not (directly or indirectly) depend on the poblesec plugin.

Steps to reproduce:

1) In a development branch, grep for "poblesec" in the pigment plugin:
    $ grep -rn --include="*.py" "poblesec" elisa-plugins/elisa/plugins/pigment/*

Expected result: empty output.

Current result:

elisa-plugins/elisa/plugins/pigment/dbus_frontend.py:47: path = "/poblesec"
elisa-plugins/elisa/plugins/pigment/pigment_frontend.py:753: main = self.retrieve_controllers('/poblesec')[0]
elisa-plugins/elisa/plugins/pigment/widgets/indicator_progressbar.py:173: full_indicator_resource = 'elisa.plugins.poblesec.folder'
elisa-plugins/elisa/plugins/pigment/widgets/style.py:17:from elisa.plugins.poblesec.notifying_dict import NotifyingDictionary
elisa-plugins/elisa/plugins/pigment/widgets/theme.py:192: #path_to_watch = "C:\Users\Anna\elisa\dev\relook_main_menu\elisa-plugins\elisa\plugins\poblesec"
elisa-plugins/elisa/plugins/pigment/widgets/theme.py:204: path_to_watch = r"C:\Users\Anna\elisa\dev\relook_main_menu\elisa-plugins\elisa\plugins\poblesec"

One more poblesec little dep in pigment: widgets/data/osk_qwerty.xml which doesn't seem to be used anymore

@Phil: indeed, I missed this one. I'll remove it.
