Fix for bug #4496
- Toolbox select menu in faceselect mode was calling object mode
functions.

Bugfix #4491

Sequencer: Image/Movie strips were printing in a 120 byte array, whilst
filepaths and names can go up to 240 now.

Bugfix #4488

On file load, a Curve deformation was not initialized when it
wasn't in a visible layer.

Bugfix #4475

Sequencer effect "Glow" did not work for float images (like render result).
Reason: threshold value for glow was still integer range.

Bugfixes from own collection:

- when renderwin exists, but not used for render, the ESC timer check still
could return ESC event, due to missing flag clearing.
(For example in sequencer, a scene strip did not update on frame advance)

- option 'single layer' set in combination with render "Do Sequence" didn't
free the pushed layers.

- Bug fix #1931
metacubes shouldn't disapear, when dx, dy, dz is too big, thanks
arsouille for pointing at right part of code (it was the oldest bug in
bug tracker)

Version patch for 2.41 saved files that had unsupported passes set.
Settings for unsupported passes are cleared now.

rolling at different views would change speed because the roll detection only realy detects if we're rolling, but not by how much.
Just clamped a max roll angle so you dont notice this.

Posemode was missing a "countall" call with pose mode select/deselect all. while adding this I noticed that lattice and metaballs were also missing countall() calls.
Added countall to metaball select, undo, duplicate (all the obvious places) - but its possible coultall() could be added to other functions especialy for metaballs.

previous commit to editface made it impossible to leave faceSelect mode of the object was in an unseen layer.
Now you can leave faceSelect/UV mode while the object is hidden but not enter it. This is how editmode works.
Tweak to crease comparison.

Added select similar crease to edge select groups. Needed this recently.

Fixed a bug where face flags could not be set because of the faces existing flags.
A problem with the current flag seting in Mesh is that Mesh needs to know of all possible flags or setting a flag can raise an error from the faces own unrecognezed flag.
also stopped the active face flag raising an error so pythoners can do face1.flag |= face2.flag without checking for active face flags. if the flag is a part of the arg its removed quietly.
Checked Mesh flags, face modes and edge flags, should all be ok now.

Plumiferos report:

The new Material "LightGroups" only worked with lamps in visible layers.
Now also lamps from the group that are not visible are included for
rendering, ensuring that a lightgroup always works on that material,
disregarding layer settings (unless lamp is type 'layer lamp').

Plumiferos report: Ipo for material 'hardness' didn't go beyond 128

(Note; this value is stored in the curve when you make it, so you have
to remove the curve and insert it again...)

Bugs #4488 and #4431

Sequencer:
Removing feature that allowed live updates of render progress while using
scene strips. In 2.41 and older this also happens invisible, and ESC from
it works now anyway.

Two reasons:
- it is quite annoying, especially on quit renders
- new 'render to window' conflicts too much with the sequencer window
option that shows previews (in code as well as functional!)

== Frameserver ==

Set SO_REUSEADDR on server-socket, since otherwise, frameserver will barf on
second start.

Bugfix #4457

When faces (like in cubes) have exactly 90 degrees angles with other
faces, the check for a vertex-normal flip became random, caused by the
infamous bad floating point resolution.
Solved with including FLT_EPSILON in the check.

Also: minor optimize for readability and removed dutch function name
(contrpuntnorm -> check_vnormal)

prev commit broke canceling a fly, works again.

Bugfix #4483

Fix for bugfix! The code added to solve Driver lag should not be called
when Bones in Armature are drivers (only when Objects are drivers).

Bugfix #4480

Material Node trees needed support in IpoWindow still, it was only showing
the Ipo for the (defunct) base material. Now it follows the active Node.
