CraftBeerPi 4 allows arbitrary code execution

URL GET parameter "logtime" utilized within the "downloadlog" function from "cbpi/http_endpoints/http_system.py" is subsequently passed to the "os.system" function in "cbpi/controller/system_controller.py" without prior validation allowing arbitrary code execution. This issue affects CraftBeerPi 4: from 4.0.0.58 (commit 563fae9) before 4.4.1.a1 (commit 57572c7).
