UI: Show message in transform panel when no metaball elements are selected

The complete lack of a transform panel was confusing enough to spawn
this question: https://blender.stackexchange.com/q/169074/599
Displaying a message instead of nothing is more consistent with the
behavior of the mesh transform panel anyway.

RNA to Manual: Update links

GPUFramebuffer: Fix compilation issue with designated initializer in C++

GPU: Fix MSVC compile errors

Fluid: Added new option to control the maximum number fluid particles in the simulation

New option that lets users the define the maximum number of fluid particles that will be allowed in the simulation. This can come in handy, for example, to ensure that the particle count will not exceed the hardware capabilities, or to avoid excessive amounts of particles in a scene.

Fluid: Updated Mantaflow source files

New files contain updated sampling function (support for maximum number of particles cap).

Fluid: Cleanup unsed file format options

File format options for noise and particles are not needed anymore (since OpenVDB update).
