Suggest required entities

[xsebek]

Currently, the exception thrown when the robot is missing some capability looks like this:

│ ───────────────────Log────────────────── │
│                                          │
│ missing device(s) needed to execute      │
│   command 'blocked'                      │
└──────────────────────────────────────────┘

Some commands are obvious, like drill requiring drill, others like blocked requiring scanner should be probably mentioned in the exception message.

In my mind there are three cases:

1. The player knows the necessary entity but the base/robot does not have it.
2. The player does not know the required entity.
3. There is no entity that the player could obtain to gain the capability (e.g. the CGod capability).

Giving a nice message to each of those cases could be slightly harder, but would IMO help beginners a lot.

Yes, I have thought about this before, thanks for opening a ticket. In theory it shouldn't be too hard to write some code to do reverse lookup of the device(s) that could provide a given capability. And I like your categorization of the different cases that could cause this.
