The Coming of TweakScale

ADDED FEATURES:
Included TweakScale in Impossible Innovations. This drastically changed
the part layout. Here's the new system:
Engines:
There are only 4 deuterium engines now; a standard model, a
High-Efficiency model, and a Low-Efficiency model.
Added a new CL-20 booster and tweaked lots of the engine settings for
all CL-20 boosters.
ALL engines are fully rescalable from 0.625m to 7m.
Tanks:
There are now only 3 deuterium tanks, varying only in length.
There are only 2 tritium tanks; a stackable and a radial type.
ALL tanks are rescalable.

I added 2 new ships to the VAB ship selection; an Impossible Lander and
The Impossible Missle of Doom.

There is now only 1 dead weight. The dead weight now has a resource
called "Lead." Lead adds the correct amount of weight per unit (liter)
added to the part. The larger the dead weight is upscaled, the more lead
it can hold.

Engines can now be requested for testing in contracts.

There are now only 2 kind of rescalable parachutes; a top-stack one and
a radial one.

Solar panels are rescalable.

TDRCS ports are now rescalable.

Poofing part is now rescalabe.

Both probe cores are now rescalable.

There is now only 1 kind of stackable battery pack.

CHANGED FEATURES / NOTES:
THIS UPDATE WILL BREAK EVERY SHIP THAT USES IMPOSSIBLE INNOVATIONS
PARTS, WITHOUT EXCEPTION.

I have left the hydrogen processing system, the reaction wheel system,
and the ionized wing out of the TweakScale system for now. They will
come eventually.

I played with lots of part prices and settings.

The command pod will never be rescalable, and neither will the struts.

I left the radial battery pack out of the TweakScale system because it
will be replaced soon.

REMOVED FEATURES:
Treeloader is no longer! I will be using TechManager in the next
release.

I removed pretty much every engine and tank, except for the ones
currently implemented.

Removed the Impossible Innovations Heavy craft from the VAB.
Last-Minute Additions

+Added an 8x deuterium tank
+Gave the Radial Tritium tank the proper Model
