Snapshot config - change to how this gets included

[Nazgolze]

Will generate this based off of the default config instead of maintaining 2 config copies

Needs to be done for both 0.9.x and 1.0.x

@Nazgolze Do you mean to use same config.json from core instead of having seperate snapshot.json file? Yes I believe it will be work, but we need to compare both files to see any significant config changes.

I believe the following need to be changed:

• port
• logFileName
• db.database
• loading.loadPerIteration

Additionally those options should be changed to prevent unexpected issues:

• version
• minVersion
• peers.list (empty)

Please, prioritise this issue. Thanks

We need to ensure .fileLogLevel is at least info (not the case with betanet for instance)
