Compile fix. Also fixed a few "unused variable" warnings

Make convex packing default setting for irregular packing operator for now

WIP packing: concave support for iterative solution search

Merge remote-tracking branch 'origin/master' into soc-2016-uv_tools

WIP Packing: working concave support.

Functionality is there, still needs optimizations and initial upscaling for best results.
Cleanup commit coming, this will also re-enable iterative computations

WIP packing: continue working on concave boundaries support

Merge remote-tracking branch 'origin/master' into soc-2016-uv_tools

Small fix. Also store number of decomposed hulls, handy to have available during later computations

Quick fix for Select Overlapping UVs operator

Add new packing to keymap and UV menu

Merge remote-tracking branch 'origin/master' into soc-2016-uv_tools

WIP Packing: Concave hull decomposition

WIP packing: initial chart boundary computation

WIP packing: continuing implementation of concave hull support

Merge remote-tracking branch 'origin/master' into soc-2016-uv_tools

Added initial "Use concave hulls" option to operator

Added point inside triangle check function for concave shape decomposition

Small tweak for margin computation

Merge remote-tracking branch 'origin/master' into soc-2016-uv_tools

Move flushing uvs including selection tags to own function

This fixes crashes when unwrapping a mesh for the first time
