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

fix in pointcache: make sure file is saved before trying to write liquid cache

cleanup for filenames and classes: SMOKE -> FLUID

now multi-view can work with more than 2 cameras

solve the camera number limitation by iterating over main->movieclip.

Multiview tracking count clip using main.movieclip

- using open clip given by main->movieclip
- haven't set up clip pointer using main.movieclip

Fixed spray mode in vertex paint.

Merge branch 'master' into soc-2016-pbvh-painting

Curves: Chamfer and offset operators

Offset operator: Fixed it to work with vector and free handles.

Chamfer: The operator now preserves all settings from the handles it is modifying (radius, tilt, weight, handle type, etc...).

Merge branch 'master' into soc-2016-layer_manager

now using scene gravity in all mantaflow scripts (smoke and liquid)

refactored mantaflow scripts

Quick fix for Select Overlapping UVs operator

Curves: Offset operator

Offset now works with auto, align and vector type handles.

Add new packing to keymap and UV menu

Curves: fillet and chamfer

Added support to fillet and chamfer cyclic splines.
Occasionaly, with no apparent reason, the following assertion fails

blender-build/blender/source/blender/blenlib/intern/BLI_ghash.c:458, ghash_insert_ex(), at '(gh->flag & GHASH_FLAG_ALLOW_DUPES) || (BLI_ghash_haskey(gh, key) == 0)

Merge branch 'master' into soc-2016-multiview

Curves: Fillet and chamfer

Fixed a calculation error in the fillet operator. Limited the chamfer algorithm to just run on the points inbetween the first and the last handles, since it makes no sense to chamfer the start of a line. This brings a problem with cyclic splines though, which will be addressed in a later commit.

Curves: Fillet and chamfer operator

Replaced calls to memcpy with BezTriples with calls to ED_curve_beztcpy, to prevent errors.

Curves: Operator's interface

Added interface options to call all operators. They are available on the tool shelf, under Curve Tools->Modelling, and on the Edit Curve Specials menu.

Curves: Offset operator

Added support for collinear handles and cyclic splines.
Changed the way offset direction is corrected. Previously, the code checked for intersections between the offset spline and the original one. I replaced this with vector calculus.
