Common defaults should exploit COIN_MINER_OPTS where possible

[LuKePicci]

We have more than one case like this where we should have exploited COIN_MINER_OPTS instead of suggesting this in comments:

nvOC_by_fullzero_Community_Release/1bash.template

Line 837 in e7c1745

AION_OPTS="--algo aion" # If using GMiner use" --algo 210_9 --pers AION0PoW" with Z_EWBF use "--algo aion"

It should just be like this:

AION_Z_EWBF_OPTS="--algo aion"
AION_GMINER_OPTS="--algo 210_9 --pers AION0PoW"

This involves GMINER, Z_EWBF and XMR_Stak at least
