SMBEdit 0.1.9

Bugfix:
Blueprints with rail based turrets and other docked entities will now work.

Details:
Due to a bad if statement turret files where not dealt with but were mentioned in the meta file as if.
That caused a blueprint to not appear in the blueprint cataloge.

Feature completed:
SMBedit has now a full set to smooth out edges:

-aw, --auto_wedge
-at, --auto_tetra
-ah, --auto_hepta
-ac, --auto_corner

Bugfix:
Auto-shaped Std./Adv Armor blocks should no longer appear damaged.

Auto-shape works now. Something must have broken when I cleaned up code. I still do not know what broke, but I made a workaround until I find it.

New features:
'sment' files can now be used as input. There is still a restriction that if the input is a sment file, the outpul is expected to be, too.

Bugfix:
- reading from blueprints meta files with no datatype 2 caused faulty meta file to be written
- entity classification is now hidden if it is not a ship or station

The tool can now automatically set wedges at edges and and tetra at corners.
Sadly hepta and corner blocks will require a bit more effort.
