Renames in class attributes so patchers compare better

self.srcFiles, self.sourceMods --> self.sourceMods in import patchers
I need to somehow unify this mess
Added # TODO: logging and _plog() - moving on
More logs unified

Notice faceMods -> sourceMods
And more

_(u'Source Mods/Files') -> _(u'Source Mods')
Attributes self.class_mod_count -> self._mod_count (gosh I hate this kind
of differences)
More class_mod_count + some formatting
self.srcMods - to better unify the logs

_(u'Source Mods/Files') may have its uses...
