Qt returns "Brazil" as country of QLocale("pt") instead of "Portugal". This conflicts with QLocale("pt_BR").
Rename the pt.ts to pt_PT and put a language mapping in tx's config for that locale.
Closes#4776.
Change project directory structure according to application structure.
Change 'nox' configuration option to something more meaningful 'nogui'.
Rename 'Icons' folder to 'icons' (similar to other folders).
Partially add 'nowebui' option support.
Remove QConf project file.
