…ted lane vehicle types

…uality

When `null`, the speed will be applied to all lanes
_except_ those with `None` direction.

Removes loop of directions.

This is simplified to take advantage of the updates to
`SpeedLimitManager.Instance.SetSegmentSpeedLimit()`
in which lane direction specification is no longer mandatory.

It wipes out several loops, particularly over segment lanes.

Completely useless warning for:
"A closing brace within a C# element, statement, or expression is preceded by a blank line."

Useful for checking if a segment has at least one matching lane
for `LANE_TYPES` and `VEHICLE_TYPES`.

It's a relic from older incarnation of speed limit tool.

`AnyApplicableLane()` will never return `true` if
either of the relevant params are `None`.
