GP: Add to stats number of objects/selected

This information was not visible when select a GP object and can be useful.

Brush: re-order sculpt tool enum

Order is now used by the tool-system,
separators currently not supported.

Cleanup: naming

Merge branch 'master' into blender2.8

BMesh: backport minor changes from 2.8

Cleanup: includes

BMesh: avoid incorrect/invalid matrix calculation

- `BKE_object_scale_to_mat3` was used to get the worldspace scale,
without taking constraints, parenting etc into account.
- Don't pass object's into BMesh API, (prefer matrices instead).
- Avoid matrix invert for each edge-angle calculation.
- Avoid 2x matrix multiplies when looping over edge pairs.

Fix 'Load Factory Settings' loosing the keymap

Caused by recent move to Python based keymaps.

Merge branch 'master' into blender2.8

PyAPI: add imports arg to BPY_execute_string

Allows for avoiding `__import__` in expressions,
was already supported for BPY_execute_string_as_* API calls.

Cleanup: style

Fix missing tips for some RNA Object API functions parameters.

Without description, parameters are not documented at all in API (not
even their type)... Always nice to have a short description anyway.

Also fixed a few other issues in existing descriptions.

GP: Make Sculpt and Edit Toolbar consistent

Multi-Objects: MESH_OT_select_similar worldspace completion

This makes the operator to work 100% with worldspace similarity:
* SIMFACE_PERIMETER
* SIMFACE_AREA
* SIMEDGE_FACE_ANGLE

Note from revisor (Dalai Felinto):

I'm not sure we want to pass Object * to the bmesh api, though I
personally don't see why not. Either way I group the patches together so
we can more easily roll them back if needs be.

The arrow cursor is too intrusive

This is inspired/based on the code we use for armature bone selection.
Both pick selection, and box selection should be working now.
