Crash was caused by some change in Blender Python API in 3.5.
The code below resulted in `ValueError: bpy_struct: item.attr = val: MeshPolygon.vertices: array length cannot be changed to 4 (expected 0)`
```
obj.data.polygons.add(1)
p1 = obj.data.polygons[-1]
p1.vertices = (v1.index, v2.index, v3.index, v4.index)
```
Now adding STAIR_ARROW annotation is a bit more clever - if you have IfcStairFlight selected when adding this type of annotation it will automatically:
1) define stair as it's parent;
2) add the stair as it's product;
3) place itself along the stair (it's assumed that stair direction is X+)

It was causing an error below on opening BIM Tool and probably in some other places.

Added support for sliding doors in IFC Door Modifier.
The main differences are 2d representation (https://i.imgur.com/VyEH569.png) and the door panel being placed before the lining, not after
Because of jumping between modes "bim.set_arc_index" doesn't remove newly created vertex groups on undo which resulted in error in decorator.
File "\blenderbim\bim\module\model\decorator.py", line 134, in __call__
if group_index in vertex[deform_layer]:
AttributeError: BMElem[key]: invalid key, must be a BMLayerItem
Switching from EDIT mode acts like canceling editing which seems intuitive.
Now it's also possible to add similar thing to other use of decorators - beware of the possible Blender bug - mentioned it in `ProfileDecorator.install description`
Added this change to editing of profiles, extrusion axis, roof and railing paths, extrusion profiles.
How it works:
1) You add Roof Modifier to some object that represents roof footprint.
2) Start editing path (Shift-E in BIM Tool).
3) Then you can select any edge and specify roof angles manually for each edge (Shift-R in BIM Tool)
to make side gabled you just need to set angle to 90 degrees. Preview will update automatically. You can set it back to 0 for angle to be defined automatically.
Some other changes:
- refactored decorator.py, in decorator now it's possible to supply some custom bmesh function that will be called on redraw, decorator now also can draw faces;
- changed colors for selected verts / edges to less bright, now it in more contrast to selected verts / edges color and seems much more readable;
