Missing buff for carrying rich vespene gas

[SoupCatcher]

When a worker carries a resource it gets a buff corresponding to what it's carrying:

s2client-proto/stableid.json

Lines 24352 to 24371 in 5b42959

	{
	"id": 271,
	"name": "CarryMineralFieldMinerals"
	},
	{
	"id": 272,
	"name": "CarryHighYieldMineralFieldMinerals"
	},
	{
	"id": 273,
	"name": "CarryHarvestableVespeneGeyserGas"
	},
	{
	"id": 274,
	"name": "CarryHarvestableVespeneGeyserGasProtoss"
	},
	{
	"id": 275,
	"name": "CarryHarvestableVespeneGeyserGasZerg"
	},

However, there is no corresponding buff for rich vespene gas, and workers carrying rich gas don't have any buffs.
