Use gocritic to check variable names more closely

[tehsphinx]

It does stuff like this:

devicelist/timingdevicelist.go:15:35: captLocal: `Links' should not be capitalized (gocritic)
func GetDeviceList(devices *List, Links *linklist.List, custIDs []int) TimingDeviceAnswer {
                                  ^
devicelist/timingdevicelist.go:254:14: captLocal: `ID' should not be capitalized (gocritic)
func buildID(ID int) string {
             ^
