Editmesh: Add options for selecting manifold
Manifold was defined as any edges not using 2 faces,
however its useful to have some options here.
You can now select between Wire/Boundary/Multi-Face/Non-Contiguous/Verts
Note the Non-Contiguous option is new,
it selects edges between faces pointing in different directions.
