Use lazy translation in classes

From flask babel documentation:
---
Additionally if you want to use constant strings somewhere in your
application and define them outside of a request, you can use a lazy
strings. Lazy strings will not be evaluated until they are actually
used. To use such a lazy string, use the lazy_gettext() function.
---

_() and _l() functions are aliases of gettext() and lazy_gettext()
respectively. Both functions belong to flask babel library.
