Patch: Fix Utilities Typos and Prevent Warnings

[Jeffrey Oldham]

ElementProperties.h:
  
        * Add a missing include directive.
  
Inform.h:
  
        * Permit use of std::ios_base::fmtflags for current gcc versions.
  
RefCountedBlockPtr.h:
  
        * Add a missing include directive.
  
tests/delete_test1.cpp:
  
        * Add a static_cast for conversion from float to int to avoid a
        compiler warning.
        * Add a static_cast around iterator.
  
tests/find_most_common_test1.cpp:
  
        * Change which overloaded check function to use to permit
        compilation.

Approved by     Jim Crotinger
Tested on       sequential Linux and gcc.
Unresolved:     tests/delete_test1.cpp's static_casts may reveal a testing 
error.

Thanks,
Jeffrey D. Oldham
