fallback feature so we don't have to run snmpsim on devel computers, should be adequate for now
./scripts/pre-commit.php -u -snmpsim will start an snmpsimd.py process automatically
* more pre-commit.php improvements
do not check influx-db on hhvm
Use parallel-lint to increase lint check speed and improve output
Add option to print out the commands that would be executed, makes it easier to modify them and run by hand
Fixed a couple of bugs
* Integrate the environment check
Flip it so we don't interfere with command line users
