Looks for hardcoded text attributes which should be converted to resource lookup

Hardcoding text attributes directly in layout files is bad for several reasons:

* When creating configuration variations (for example for landscape or portrait)you have to repeat the actual text (and keep it up to date when making changes)

* The application cannot be translated to other languages by just adding new translations for existing string resources.

In Eclipse there is a quickfix to automatically extract this hardcoded string into a resource lookup.
