Localize .loc and .pkg content based on TRANSLATIONS

If developer specifies "CONFIG += localize_deployment" in .pro file,
the generated .loc and .pkg will now use translatable strings from
.ts files defined in TRANSLATIONS. The .ts files must have an
underscore and Qt language code at the end of the filename body
to be compatible with deployment localization. E.g. myapp_en.ts.

Running lupdate will generate these entries into .ts files:
- Application short caption
- Application long caption
- Package name
- Smart installer package name
