Fix for booleans with edges overlapping faces exactly

Minor edits - enable dissolve by default

Support dissolving vertices created by tessellated edges

This needs to be done using different logic for boolean operations to ensure its not creating 2-sided faces.

Also make dissolve and separate into options (mainly for testing/debugging).

Allow to switch between bmesh and carve boolean from the modifier UI

Merge branch 'master' into bmesh-boolean-experiment

BMesh boolean no longer splits geometry

Duplicate geometry was created along intersections.

Merge branch 'master' into bmesh-boolean-experiment

Use BM_face_calc_point_in_face API call

Merge branch 'master' into bmesh-boolean-experiment

remove unneeded edge tagging & un-indent block

Perform boolean test even when theres no intersections

Boolean: checking index of faces wasn't reliable to tell the mesh it came from

When faces are split, the index is set to -1

Use free flag instead.

Merge branch 'master' into bmesh-boolean-experiment

Turns out face normals are needed for edge-net split

Merge branch 'master' into bmesh-boolean-experiment

Fix error with concave ngons

Failed when face-center wasn't inside the face.
copy-paste from knife tool, best make generic function eventually.

Merge branch 'master' into bmesh-boolean-experiment

Add double threshold option for boolean (mainly for testing/debugging)

Intersect operator was performing boolean, also correct NULL pointer free

Disable dissolve (for intersect testing)

This causes errors splitting the mesh in some cases,
eventually would be good to use but disable for now.
