Component cost for 3x3x3 small tanks reduced.

Huge update! I changed quite a lot of things in this, and also fixed a few things as well.

For Balanced Version:
- Component re-balance for all tanks. Specifically the tanks were balanced component wise w/ the vanilla oxygen tank and then glass was added since the tanks visually have glass on them.
- Changed all tank inventories to lower values to prevent them hoarding insane amounts of bottles.
- Fixed all sound tags in each tank definition. This changed a while back and I never had time to work on these.
- Fixed <IsAirtight> tags not setup on some tanks that should have been airtight.
- Changed build-times in-line with vanilla small tank. (1x3 2 port tanks take 5 seconds less to build than 1x3 6 port)
- Fixed PCU duplicates and PCU values are more in-line with vanilla values.

Note:
Using 1x3 2 port tanks is still 25 pcu because per-tank they only use 2 conveyors. However, using a 1x3 6 port tank has double the pcu now, because it has 6 ports and too many of these will end up lagging your world badly.

Uploaded fix for g menu crash.
