A user doesn't want to necessarily create a new Screen only because she
wants a new window.
This patch allows the user to pick the screen to use for the new Window.
If the screen picked is the active one, it duplicates it (as the old
behaviour in Blender).

Use expanded names for bmesh primitive operations
(urmv jvke semv jfke).
Use 'bmesh_kernel_' prefix,
these functions aren't intended for wide use so favor readability.
Remove BM_face_vert_separate,
it wasn't used and only skipped step of finding correct loop of face.
It might be useful to keep the search string stored in some cases, but
in most it's not useful but confusing. Especially if the string is taken
from a menu showing a different enum.
When the loop region passed in had no loops to edge-split from,
it was assumed nothing needed to be done.
This ignored the case where loops share a vertex
without any shared edges.
Now BM_face_loop_separate_multi behaves like BM_face_loop_separate.
Fixed error where faces remained connected by verts in BM_mesh_separate_faces.
This commit adds new features to the breakdowner, giving animators more
control over what gets interpolated by the breakdowner. Specifically:
"Just as G R S let you move rotate scale, and then X Y Z let you do that
in one desired axis, when using the Breakdower it would be great to be
able to add GRS and XYZ to constrain what transform / axis is being
breakdowned."
As requested here:

Notes:
* In addition to G/R/S, there's also B (Bendy Bone settings and C (custom properties)
* Pressing G/R/S/B/C or X/Y/Z again will turn these constraints off again
Turned out to be a quite easy fix. I thought the issue was that we
couldn't identify the TreeStoreElem when (re)creating its TreeElement item
correctly, because for non-ID elements that would be index dependent (=
bad for drag & drop). Turns out that we're actually allowed to store
custom data within the TreeStoreElem, the thing is just that it gets
stored as ID pointer (highly ugly and highly misleading).
Anyway, seems to work now so I won't complain too much :)
This way we can ensure the overlay to indicate where the item would be
placed if it was dropped now is always at the correct place and doesn't
mislead the user.
Two issues are remaining, they'll be fixed separately:
* Graphical feedback when dragging within the master collection is wrong
* There's some bug where collections swap places instead, Dalai will investigate
- Connectivity length was overwritten by distance to closest selected.
- Vertices used the 'island' center of the closest vertex,
even if it wasn't connected.
Now optionally keep track of the original index of used as the closest
connected distance.
To support this needed to add optional support for islands of 1 vertex.
The changes introduced in rB3e628eefa9f55fac7b0faaec4fd4392c2de6b20e
made the non-subframe frame change behaviour less intuitive, by always
truncating downwards, instead of rounding to the nearest frame instead.
This made the UI a lot less forgiving of pointing precision errors
(for example, as a result of hand shake, or using a tablet on a highres scren)
This commit restores the old behaviour in this case only (subframe inspection
isn't affected by these changes)
