Merge branch 'master' into soc-2013-sketch_mesh

I adjusted some variables names.
The modifier sends a message on screen if the system not found a solution: (The Modifier not determines if a system is soluble, the numeric solver OpenNL Superlu notifies if solution was found.)
Fix bugs:
- Load file in a correct way.
- Delete vertex co (float array) when the bind flag is false.

Code Cleanup: minor changes to laplacian deform modifier interface

Code Cleanup: style edits and avoid sqrt

Code Cleanup: includes and warnings

Changed the names of some variables.
The modifier print on screnn an alert when the user change the vertices, edges, or vertex group.

Create of new Operator for bind Laplacian Deform Modifier
The Laplacian Deform Modifier bind the initial vertexes positions.
I Modified the LaplacianDeformModifierData struct to store bind state.

Add eModifierTypeFlag_SupportsEditmode to support modifier in EditMode

svn merge ^/trunk/blender 60972:61239

Changes suggested by Campbell:
- Delete pointer to DeriveMesh
- Store face tessellation

The LaplacianDeform modifier only use DeriveMesh.
Fix bug: about only support mesh with faces

remove use of BLI_array

minor changes, remove some NULL checks for allocating small arrays.

rename rna repetitions to iterations

replace calloc for malloc in places, also minor style edits.

code cleanup: style

branch now compiles on linux (minor fixes)

Fix a bug when the user modify the vertex positions in edit mode
