Cannot change default initial asset issuance label from 'bitcoin' #371
Description
It would be nice for those creating stand alone blockchain implementations to be able to use a new parameter in conjunction to 'initialfreecoins' called something like 'defaultassetname' or something that allowed you to overwrite the 'bitcoin' label that is defaulted to.
Scenario - someone wants to use Elements to set up a standalone blockchain with 10M amount of a native asset called 'newasset'. Currently they must issue some of the default 'bitcoin' asset in order to fund a tx that creates 'newasset'. Then you can set -feeasset to newasset - which is fine - but in order for subsequent nodes to 'see' newasset's issuance they also need initifialfreecoins set to > 0 so that they are aware of the 'bitcoin' asset that was used to fund the asset creations. Which ends up being a bit of a 'work around'.
Other things to consider - can you reissue the default created asset to create more of them? Might be needed if you go down the route above. Currently I think this is not the case.
