Outliner: Fix mode column when lock object modes is disabled

When Lock Object Modes was disabled, multiple objects would be shown as
in the interaction mode even though only one object could be edited at a
time. This was not an issue for edit and pose mode because those modes
support multi object editing. But in modes like sculpt it implied that
multiple objects could be edited at the same time.

This only draws the active icon for the active object when lock object
modes is disabled, and when there is no active edit or pose object.

Outliner: Use dot icons for object not in current interaction mode

Revert the change that used a faded-out icon of the mode. That was too
cluttered.

Fix crash: exporting object from Edit mode.

Make all frames exportable; UI & filename changes

All frames are now exportable including negative ones, instead of
only 0-1000.

Added checkbox for Animation for better UI {F8622012}

File name doesn't contain frame name if no animation is being exported.

Noticed that `source/blender/io/wavefront_obj/IO_wavefront_obj.h` is
missing in the IDE's edited files list. So edited that in.

Cleanup: unused headers, minor edits in comments

Since fstream was removed, these headers are useless here.

Export multiple frames to separate files.

Frame 20 with mentioned filename `name` is exported to `name020.obj`
It should be modified to exclude cases when a single frame is being
exported to avoid overwriting what the user intended to name it.

Also a filter is added to include only OB_MESH type objects for export.

The limits on frames can be changed, the current limits are like this:
Let's say unknowingly, the user selects the maximum 1000 frames & every
file is 1 MB in size. That will quickly fill up 1 GB on the disk.
More frames add to this risk.

Custom Menu: fix display error, operator editor

Added unique name parameter for modifiers as well as MeshTest class

Fixed bug for some binary boolean ops. Fixed a memory leak.

Now the basic binary booleans work from the tool (not the modifier).
Still to do: (1) coplanar and non-connected-component cases;
(2) dissolve triangulation lines and new verts due only to them;
(3) properly transfer mesh attributes from old to new;
(4) hook up to modifier;
(5) attention to and tuning of performance.
