Forced return value in cpplint

[GoogleCodeExporter]

The cpplint returns non-zero when there is at least one message. If the cpplint 
is started from a make file, the non-zero return value will stop.

Proposal is to add "--return=value" option that forces the script return the 
given value even when there is messages (see PC-lint -zero).

Attached batch adds the option to the cpplint and it has been tested with cmake 
+ Visual Studio 2013.
