fix: small collection of bugfixed debugger hints and warnings (#801)
* small collection of bugfixed debugger hints / warnings

* 'toStdVector' has been explicitly marked deprecated

* fixed double zip naming in artifacts

* V4L2 WebUI Fix

* Some code fixes based on alerts from lgtm.com

* only execute dynamic v4l2 enum code, if V4L2_AVAIL

* very high critical bugfix ;)

* merge fix

* some lgtm.com fixes

* lgtm fixes

* undo localtime_r fix
