Subject: undo: autogenerate string get() and data() functions using a template

Do this in analogy to other types. However, here we have to convert
from / to QString. We could do this in an even more general way
by using two templat parameters: one for the Qt type, one for the
core type and define conversion functions. However, let's not do
this for now.
