Merge tag 'v0.8' into layout-module

 - tagging version 0.8
when the user saves the layout, the output file shouldn't present the <layout-block> tag - this is just internal to exchange layouts among the participants
fixing the layout manager startup, just like it was done on master
translated specific strings to pt_BR
Fixed problem where layout list wasn't displayed

The problem occured because the event to populate the list was sent
before the creation of combobox.
Refactoring code to fix problem where combobox lost event to populate its data.
Fixed missed import and misspelled variable.
