Implement rudimentary divecomputer download

Small changes to the names of elements the divecomputer download UI and
very simplistic first stab at populating the device_data_t structure.

This is lacking lots of things
- it should remember the last vendor / product used
- it should figure out which device (mount point) to offer
- it needs proper error handling

But it's a step in the right direction.
