Added research

Updated to 0.6

Fixed minor mount-point bug with triangular side wall pieces -- palisade & wooden. Now both should be more easy to place.

New Major Update:

Added round wooden roofs
Added complete palisade wall system for low-pitched roofs
Added ALL rooftop variants (6 for tile and 6 for wood)

Cleaned up more files and optimized more models.

Fixed silly typo in XML definition file

MAJOR UPDATE:

-- Reworked all of the tile roof models to clean up basic models and especially collision. Should work a lot more predictably and accurately now.

-- Added all vanilla tile roof toppers (6 versions total) in low-pitched form

Still to come:
** Will update all wood roof models/collisions
** Will add palisade low-pitched wall system
** Will add clerestory windows in stone walls

Fixed bug with component tagging that was keeping wooden walls & roofs from being buildable to a full 100% in Survival. They should all work now!

Bugfix:
-- Updated components so that tile roofs take stone instead of timber to build.

Bugfixes:

-- Removed unnecessary blueprint/research
-- Made round tile roof visible in the 'G' screen menu for the low-pitched roof kit
