Very slow trees in rocket [IP -> keeps JQ up-to-date]

[mguidon]

The modeling tree becomes very unresponsive (e.g. collapse/uncollapase). This can be emulated by:

import XCoreModeling as xcm
for i in range(1024):
	xcm.CreateSolidBlock(xcm.Vec3(0), xcm.Vec3(1))

This generates 1024 blocks in the modeler. You can also save this as a smash project and just load it.
