* add verbose examine text to gas miners so their behaviour can be understood
* no need for these to be properties
* use an enum instead of two booleans for the miner state
* require the gas miner to be anchored in order to not be disabled
* xmldoc
* pr feedback
* file-scope namespace
* it's to late to hide my transgressions in a rebase
* turns out the normal examine distance is totally fine for this
