Change of devicecond handling

[mshannaq]

In this PR I will change the device redirect condition structure in database

from (example):

{"condition": "device", "conditions": [{"computer": [{"windows": "www.microsoft.com"}, {"linux": "www.linux.com"}], "smartphone": [{"andriod": "www.andriod.com"}, {"iphone": "www.apple.com"}]}]}

to: (example):

{"condition": "device", "conditions": {"applesmartphone": "http://itunes.com/", "windowscomputer": "https://www.microsoft.com/", "andriodsmartphone": "https://play.google.com/"}}

to keep the device conditions more simple and that will make it easy to add more new devices in future.
