Grouping issues by vulnerability title

[thesp0nge]

It will be great having a command line flag telling flawfinder to group findings by security title and not by file and location.

i.e. from this:
./src/file_a.c:89: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.
./src/file_b.c:104: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.
