d75ef80f12 Get sorted list of available languages 
TessBaseAPI::GetAvailableLanguagesAsVector returned the list of languages
without sorting, so the result was random and not user friendly.

Now `tesseract --list-langs` shows the available languages and scripts
in alphabetic order.

34a89e54db Fix function ScrollViewCommand 
The format string which builds the command only takes one or two
string arguments, so the function allocated too much memory and
passed too many arguments to snprintf.

This also fixes a compiler warning (clang).

830b9c715a BLOBNBOX: Declare signed bit field 
This fixes a warning from LGTM:

    Bit field area of type int should have explicitly unsigned integral,
    explicitly signed integral, or enumeration type.

Maybe area should be unsigned, but that would require lots of other
changes, so for now signedness is not changed.
