Setting a custom frame time will result in stable animation speeds if projectM does not render at real-time speeds, e.g. while encoding a video from an audio file as fast as possible.

Allow apps to set the time before each frame, allowing for non-realtime rendering with fixed or dynamic framerates. Setting the frame time to any value equal to or greater than zero will use this value for the next frame, while setting it to a negative value will make projectM use the system time instead.
The value defaults to
-1.0, so if theprojectm_set_frame_time()method is not called, projectM will just behave as in previous versions.Also added another function to retrieve the time of the last rendered frame.
Closes #740
