Merge remote-tracking branch 'origin/master' into experimental-build

Merge branch 'master' into asset-engine

Rename types (wmWidget->wmManipulator)

Rename files and folders (widget->manipulator)

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

Cycles: Support filter strength for denoising after rendering

Minor cleanup

added global keep shards mode for cutter groups

fixes: activating clusters via percentage, add meshisland id as name in fracture too, load crash fix

ui cleanup in fluid quality and general fluid tab

Initially add widget files and get them compiling

Another temp_ branch :S This time for preparing custom manipulators core code for merge.

Claude: more WIP work towards listing content on Cloud repository.

Allow asset engines to change current dir also from list_dir function.

Rational is, in case of online repo, it may not be practical to decide
whether a path is valid or not from check_dir() callback, which should return
immediately.

So instead, check_dir() can only check whether path **looks** good, and
delegate actual path validation to list_dir (and maybe other similar functions).

That?s what is being tested with Claude engine at least.
