AI Carriers: tidy and resolve ctor order

Tidying up:

* change to use direct initializtion
* put all of member variables in alpha order
* adjust init spacing to make init values clear.
* change all member variables to start with an underscore. The reason for this isn't clear but some had an underscore and some didn't; so although I don't know what the convention was intended for this seems to be the appropriate changes.
