Added "Topological distance" option to Select Shortest Path operator

Similar to the editmesh operator: "Find the minimum number of steps, ignoring spatial distance"

Fix for "face stepping" behaviour of path calculation

Since parametrizer operates on triangles, diagonal edges of quads have to be tagged and not taken into calculation of shortest path

Rename UV_OT_shortest_path to UV_OT_select_shortest_path

Should have been commited with the UI menu entry commit...

Adding PEDGE_DIAG tag to diagonal edges of quads (parametrizer data structures are triangle only)

WIP: Select Shortest Path: Add UI menu entry for operator

UV Editor: Select -> Select Shortest Path

WIP: Select Shortest Path: Correctly set selection tags for edges of found verts of path

WIP: Select Shortest Path: Fixes to path computation

Also contains a few debug prints which are handy for now. Needs a cleanup commit later anyway

Fixing memory leak in path selection code

WIP: Select Shortest Path: Directly set the MLOOPUV_*SEL selection tags

To get the edges tagged for selection from the parametrizer data structures we need to directly set the flag of MLoopUV

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

Wip: Select Shortest Path: Tagging of found path edges for selection

Selection flags of MLOOPUV should be set in p_flush_uvs(), needs a closer look

WIP: Select shortest path - Computing the shortest path using regular Dijkstra algorithm

WIP: Select shortest path - Validate selection

Validation of the current selection, makes sure 2 matching elements are selected for path computation

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

Fix for bug in optional packing with unwrap operator

Center and scale were off if aspect ratio != 1

WIP: Added "select shortest path" operator for UVs

Main functionality still missing, calls mesh-tool for selecting shortest path if Sync Selection is checked

Added "Pack islands" option to Unwrap operator, to give artists the possibility to not automatically pack after unwrapping
