* Fix Siklu Version/Serial
Siklu allows for two software images. We must first determine which SW bank is "running" in order to report the correct version.
Also adding correct Serial Number detection for Siklu devices.
* Update siklu.inc.php
* Update siklu.snmprec
* Create siklu.json
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
