malloc'ed char-string gets delete[]d

[Former user]

Originally reported on Google Code with ID 258

While studying the source code (pulled from github), I found that the 
char* buffer in _doFormat() is created using the C-style malloc() 
allocator, but is destroyed in operator<<() using the C++-style delete[] 
deallocator. This asymmetry is really bad and should be fixed, either by 
using new[] in the first place or free() in the second.

``` Also affected, core/evaluator.cpp: operator<<() calls HMath::formatFixed and delete[]s the result. ```

``` Here's a fix, created against commit '5bda34...'. 'testhmath' runs clean. ```
