[Fast import/export] Fixed build issues on windows

LANPR: Fixed triangle culling algorithm errors.

Fix: Build error with clang on windows.

clang does not seem support the static_assert with
message overload.

Outliner: Add sync selection property

Adds a toggle to each outliner for synced selection

Merge remote-tracking branch 'origin/master' into soc-2019-cycles-procedural

[Fast import/export] Added binary STL

Merge branch 'master' into soc-2019-outliner

Outliner: Redraw on constraint reordering

Rather than restricting which constraint actions redraw the outliner,
all will (similar to modifiers). This will redraw on constraint
reorder

Outliner: Draw constraint icons

Draws constraint icons in the outliner for bones and objects. The
only icon that has an issue is the Action constraint icon, because
it doesn't have a specific constraint icon, so it is drawn white
instead of blue.

At first I tried to replicate the code for modifier icons, then
I found a solution using `te->directdata` that worked for both
objects and bones. It works well enough, not sure if that simpler
solution should be used for modifiers too.
