Some block callbacks and additions

To keep it short, there are a few logistical blocks from SE1 that would be super useful to have in SE2, and a few tweaks to existing blocks I might recommend:

Small ports on the sides of the 2.5m Hydrogen thruster: Unless there's going to be a cap on the fuel volume per second through conveyors of a given size, this would help save on some pcu and conveyor work to fuel thrusters people are likely to be putting down chains of anyways, and they already have space where they'd go that makes them look like they were planned to be there at some point.

Conveyor Converters: The converters in SE1 had a lot of utility, as the three small ports on the large face made it easy to put 2 such converters together to produce a relatively compact .5m or 1m offset when you had large ports but didn't need a large-port system (such as if you were offsetting thrusters relative to a large tank). The side ports also allowed much more compact attachments to larger ports for small craft, allowing a large port to "90" in to a small port in 1 conveyor block instead of 5 (without using connectors as glorified conveyors).

Small tanks: Sometimes you don't need to carry the H2 to fuel a ship or the O2 to last you a month. Sometimes you just need to top off your jetpack and only need the air to last for a few hours in a small craft that regularly reconnects with the base. With what we've got now we're back to people fitting whole O2/H2 generators to small craft just to supply their suit again because they take up less space than a storage tank.

.5m Windows: How is anyone supposed to sculpt a front-windscreen for a flying motorcycle out of windows the size of a car-door? Speaking of which...

Saddle Cockpits: How am I supposed to get people excited to play with the prospect of flying around the 'verse as a bounty-hunter on their space-hawg if we don't have the a saddle-seat to control the hwag from?

Anyone else got other blocks or block-modifications they'd really like to see?
