Use searchable dialog for tag and aspect/contact list
* Remove seperate fragments for both cases * Make use of opoc/SearchOrCustomTextDialog * Basically also removes all fragment swaps * Only two fragments are stream and podselection * Pod logout restarts app * Thus long known Android Supportlib bug can't occur * Fixes #198
