following mikko's comments on push #17 (part 2). Interfaces changes, the most notable is adding option flags to initSlicedFindPath that can cancel the any-angle search
changed the NavMeshTesterTool so that pathFind and straightPath use the default options (i.e. not any-angle) while sliced path uses the any angle search.
changed the remarks and value of RAY_CAST_LIMIT_PROPORTIONS
Merge branch 'master' of https://github.com/axelrodR/recastnavigation
bug fix: returned path had duplicates of nodes
bug fix: finalizeSlicedFindPathPartial() did not handle the case of DT_NODE_PARENT_DETACHED at all.
changed the default options of the pathfinder to 0 (i.e. no raycasts), changed the the tester tool to display all points along the sliced path (a better default for non flat terrain).
