3.1.4

Adds an -s (strict) command line switch to the codesniffer-run script. This is a coordinated change with the Loadsys Coding Standard to help reduce the noise of TODO markers in the code from masking legitimate code sniff warnings. By default, TODO warnings will now be suppressed in output. To reveal them, include the -s switch, which may be useful in CI builds to enforce the strictest possible ruleset.
