Add ability to process received collections directly as List with specified type

[softberries]

At the moment processing list with ServiceRestClient has to be done with the following

.anObject().ofType(List.class);

This of course is unchecked and in other words sucks. What would be nice is to have smth like this:

andExecuteFor().list().ofType(String)

which would process received list with specified type

This issue is invalid, after further investigation and contacting extraterrestrial forms of life throughtout the night I have found out that its enough if we instead of (eg. for list of strings)

.ofType(List.class)

do

.ofType(String[].class)

This works with simple types, but we can't do this trick with List [ DTO ] directly. There is an option to use TypeReference, but it needs a lot of work to refactor in a way to make this usable.
