Fix inconsistency with electro refire time

All 5 bal-wep- configs have had their electro_secondary_refire and _refire2 switched around. This change makes it so that refire1 affects the time between 2 alt fire bursts while refire2 now affects how quickly primary fire can be fired after alt fire has been fired.

The refire timer is reset with each ball fired in the burst. I adjusted weapon balances by removing 0.4s from old refire2 / new refire1 to keep the old 1.6 seconds, the current is still effectively 1.6 seconds if all 3 balls are fired as it's reset twice with 0.2s animation time delays. If only 1 ball is fired then the delay is 0.4 seconds shorter, 1.6 -> 1.2, I don't see this as a problem but as an improvement as it rewards those who pay attention to what buttons they press.
