Bugfix #25636

On using loop-selects, the active vertex got cleared, it could still
simply indicate one of the vertices of indicated edge to become active.
That keeps the Ui for vertex-groups drawing correct, for example.

Also made loop-ring select store active edge for tools, like the loop-select.

Fix for [#25633] Particles display switching causes crash when Velocity disp. ON
* Particle draw data wasn't freed properly in some cases.
* Velocity + circle draw type also crashed due to missing null pointer check.

Fix for [#25637] curveguide forcefield(Kink: Braid) + particlesystem cause crash by Null Pointer in some cases
* Missing null pointer check.

error in last commit, also skip getting vars for wm_operator_reports() when there are no reports.

remove unused vars & avoid some clang warnings.

checking wrong null pointer in edit_modifier_poll_generic().

apply fix from r34275 to BLI_dynstr_appendf(), dont chop off last character for >256 length strings.

new startup.blend with official io addons enabled,
also include STL since this is an important format which we can support officially.

moving io scripts to 'addons' dir in extensions svn, leaving MDD format since I dont maintain this.

Todo item #19816: Wave modifier does not affect Curve Paths

Added new option for applyong modifiers on splines' points. This moves
tesselation point and path would be affected by modifiers which are applied on
splines' points.

add icons to show community vs official scripts as well as buttons to filter by support level (currently all scripts default to community)
note: we need better icons for this.

also formatting edit for ply import.

rename bl_addon_info --> bl_info, because this isnt necessarily used for addons.

Transform tweak:
2D Editors using the standard translation transform tool no longer
have their values converted. For instance, it simply didn't make much
sense in such editors to be showing frame numbers/timing in terms of
meters/inches.

Bugfix [#25617] HOME Key in fcurve editor doesn't center properly

* When euler-rotation F-Curves had a single keyframe only, the view
would be artifically extended to fill up to 57 (this comes from the
radians to degrees calculations) due to a combination of the bounds-
finding function enforcing a minimum separation of 1 unit between
min/max. This has now been moved to the operator-level where it gets
applied AFTER these conversions have taken effect

* F-Curves with samples only (i.e. baked F-Curves) would be ignored by
these operators. Was caused by using a poll calback that only
considered whether there were keyframes. Hopefully this is sufficient;
otherwise a hybrid poll method will be needed.

Driver creation hack:

Drivers created from the Properties Editor for Materials and Textures
will now be created on Object-level instead of on their owner
Material/Texture as for their keyframes.

The intention of this hack is to allow users to be able to easily set
up drivers for materials and textures. Without this hack, users would
have had to do this manually via the Datablocks editor (I've described
this method a few times in detail, though this still attracts
complaints), as the way the depsgraph works does not allow ID blocks
other than Objects and directly-linked Object data to be driven. As a
result, although this hack can be done for these two cases, there are
no workarounds possible for Scene and Scene-linked settings.

There are 2 issues that will be noticed with this approach:
1) There may be confusion over why the drivers are found under Object
level and not Material/Texture level.
2) Driver status will not be shown in the buttons, leading to attempts
to try to keyframe the properties directly later and subsequent
confusion when finding that that won't work.

However, these are the sacrifices we'll need to make to get easy-setup
working in the meantime until the proper fixes can be done.

add ply import into the file menu.

initial 2.5x api port. basically working.

Reverting r33930 and r34202, which were related to bugs #21825 and
#25554. As found by Daniel Lara (Pepeland) in #25554, the original
problems in #21825 all stemmed from the ChildOf constraint there
having an incorrect inverse set, which was altering the final results.

Now Auto-IK works nicely for old rigs again (i.e. FK arms on BBB rigs)

python3 updates:

pep8 cleanup.
