Upgrade times and cost lowering for better dynamics •••••(compete) Nakamura

The game currently forces players to stick to one or two ship classes at best due to very costly and time consuming research. To resolve this, i'm going to change the costs and times it takes to research each ship class-wide technology.
Example: spending 5 minutes of research on lvl3 fighter damage is one of the reasons it is so hard to transition out of it.

Also, spending 10k resources on the third level of super capital upgrades will make the game unplayable in the late stages.

The changes I'm going to add is very numerous, so I will not be able to log them properly, as such.
Hopefully dynamics will be improved by a great extent.

Task complete. We're close to release again.
