Fix for Item10564 avoids the crash, but the handling could be improved.

• Obtain the list of IncludeHandlers and verify that the handler exists before attempting to eval it.
• Return a more meaningful error message to the user:

%<nop>TMPL:DEF{"bad_include_handler"}%   %MAKETEXT{"Warning: Can't find handler for '[_1]', available handlers are: '[_2]'." args="<nop>%PARAM1% %PARAM2"}% %<nop>TMPL:END%

Changing this task to remove it from the 1.1.4 planning. I don't see that there is a big benefit to trying to enhance this, and it would add overhead to every INCLUDE.
