This patch fixes many minor spelling mistakes, all in comments or
console output. Mostly contractions like can't, won't, don't, its/it's,
etc.

The problem is caused by a lack of prediction in the `isect_line_segment_tri_v3`
that incorrectly confirms some intersections of coplanar segments to the triangle.
The solution is to use another algorithm to detect intersections.
This also resulted in a slight improvement in the performance:
- 1min 17sec to 1min 6sec in my test file

By default watertight intersections are used,
For callbacks where its not needed,
BLI_bvhtree_ray_cast_ex can be called without the BVH_RAYCAST_WATERTIGHT flag.
Fixes T45286
Now cut lines detect vertices that they pass (almost) exactly over
and snap to them, to avoid making verts vert close to other ones.
Added radius arg to BKE_bmbvh_ray_cast so that can detect an obscuring
face when the ray might otherwise go exactly between two triangles.
Needed an isect_line_tri_epsilon function for similar reason.
Fixes last part of bug #35002. Other knife bugs still present but
getting this commit in now before continuing bug fixing.
internal improvement to editmesh_bvh.c
- optionally pass cage-coords as an arg, rather then calculating the coords in BKE_bmbvh_new(),
since all callers already have coords calculated.
- de-duplicate coords creation function from knife and bmbvhm, move into own generic function: BKE_editmesh_vertexCos_get()
- remove unused members from BMBVHTree
- move per-raycast vars from BMBVHTree into per-callback structs (weren't threadsafe).
- simplify BKE_bmbvh_find_vert_closest().
