# About the pull request
Split off PR from #8284 because im planning to add solar devils to the
spawn pool

Vai spawn chance is now 10 (regular) and 10 (covert) prob to spawn
instead of 20 and 20
Pizza Galaxy ERT is now 2 prob to spawn
For reference, there is the current spawn chance of every ERT in the
game, sorted by probability (and groupted by faction)
> VAI : 20 + 20 (VAIPO + VAISO)
CMB: 10 + 20 (marshals + Riot control)
CLF: 20
PMC: 20
Freelancers: 20
UPP: 20
RMC: 15
Xenos: 10 (Prime + Ferals)
Pizza: 1 

For a total of 176

VAI is the most likely faction to spawn (roughly 22% of the time) by
quite a decent margin, with only CMB coming close to them due to the
riot ERT.

After this change, the total is 157 probability total.

# Explain why it's good for the game
VAI spawn too often, making them rarer means we see different ERTs more
often.

The doubling of pizza galaxy chance is because I've still yet to see
pizza ERT naturally spawn ingame even after I added it in #5662 and the
number of ERTs has only increased since then, making it rarer and rarer.

# About the pull request
in #7193 I wanted to add the SG frontline mode only, but couldn't figure
it out until now.
Solar devils Smartgunners are now stuck on frontline mode, to emulate
the PVE feel, to compensate, they get 15% bonus damage multiplier.

Solar Devils RFNs spawn with 30 metal (from 50)  (split from #8284)

# Explain why it's good for the game
Solar Devils SG having frontline mode fits in with the PVE 'soul' of it,
the 15% damage boost is nice but I doubt it's going to make the SG too
overpowered, as they are forced to watch their firing lines instead of
just holding m1 from behind a horde.

The metal nerf is to discourage the solar devils RFNs from making a mega
FOB when spawned by admins for events groundside, especially as I plan
to make the solar devils a naturally spawning ERT.
