Update floating controls paneltype for the new userprefs option.

Move floating controls option to the Interface tab where it fits better.

UV mirrored unwrap
====================
* Code cleanup, avoid duplication.

Mirrored Unwrap
================
* support for ngons in regular unwrap.

Mirrored unwrap
================
* better support for regular unwrap, fixed incorrect indices of edges
when calculating seams, made it possible to take seam on mirror border
into account so that mirrored part can be "cut" during unwrapping.

Solve compilation erro (missing 'r' intended)

Support mirror unwrap for normal unwrapping. Only non-ngons in this
commit.

UV mirrored unwrap
===================
* Separate common mirror functionality from modifier files to BKE_*
files
* Now subsurfed unwrap can flush the result of the mirrored mesh to the
solver
* TODO: add support for regular unwrap, pack the result to 0.0-0.5 range
if the appropriate mirror uv option is selected in the modifier

Another experiment with arranging the two-dimension scale/translate manipulators such that they don't look so cluttered.

Attempting fix for strange issue with menus becoming unresponsive and
flickering of floating panels.

Add a button to switch back to object mode.

Better fix for last fix

Fix silly crash on meshes without modifiers due to own commit

Introduce an operator which switches to edit mode and activates a specific edit selection mode at the same time. This lets a designer create buttons that go to a specific edit selection mode when the user is in object mode. Use this operator to implement more functionality for the floating controls.

* Cleanup of subsurf unwrap code

Now take subsurf levels and type from the modifier stack (Now simple
subdivision will work too). Subsurf unwrap won't work if there's no
subsurf first or after mirror in the modifier stack. This is done to
alleviate having to set subsurf levels in two places, usually user will
want the tool to autodetect the setting from the stack. This sets the
paradigm that will be followed by mirrored unwrap as well.

UV transform correction
========================
* Fix crash when moving single vertices or vertices/faces not attached
to faces.

UV unwrap mirrored
=====================
* Dummy GUI/RNA operator properties

merge with trunk 49039

Created floating buttons for changing the edit selection mode, vert edge or face. These buttons work similar to the manipulator buttons in that pressing one shuts off the others, unless shift is down.

Update the 3d view after the floating controls option is changed.
