if you switch ifc_class then relating_type_id can become invalid and we wasn't taking it into account
Also fixed bunch of warning like `pyrna_enum_to_py: current value '17' matches no enum in 'BIMModelProperties', '', 'relating_type_id'`` when some ifc_class has N related types and then you switch to other ifc_class that has less than N related types.
This reverts commit 4bc987924d since there was some unintentional changes.
Now when you use select_type in object properties - ifc class and related type gets selected in the BIM Tool - https://i.imgur.com/drIHYDz.png#3318
Basically if current mesh curve is non consequtive we handle it in similar way to b03c4da7b - convert it to curves using Blender and then save them to ifc.
The advantage is that it creates less curves in ifc because mesh method wasn't able to detect separate curves correctly if vertex order was messed up (usually it is) and it would create separate curve for each curve segment.
I've also replaced figuring vertex duplicates with `bmesh.ops.remove_doubles` manually with `bmesh.ops.remove_doubles` and it's now much faster. In some cases because of the manual calculations it was taking too long - in #3233 Ryan mentiones that it freezes blender, it wasn't really freezing Blender but to finish calculations it would take 10 minutes.
It was a bit confusing UX since when you finish editing arbitrary profile path the data is already saved in ifc but you were still in editing profile properties
IfcRelConnectsElements type of connection wasn't handled properly resulting in errors.
Now you should be able to see connections for connected slabs, walls etc - https://i.imgur.com/LpFBKBC.png

now we're going to store all texture paths in .ifc as posix to keep them working if .ifc moved from one platform to another
previously it was saving all paths as absolute
