Cell amount on the Engineer HUD

It would be very nice if you didn't have to select the wrench to check how many cells you have. This way, you would be able to charge up your Railgun without having to stop between every few charges to see how many cells you have.
Having to change to your wrench to check your cell amount is both a waste of time to do, and for someone like me who uses their Q button a lot, it means you have to switch back to your SShotgun, then back to the Railgun if you want to be able to quickly swap to your SShotgun at anytime while charging rails (since the Railgun is not always the best for combat, but is deffinetly very useful)
