Fixed bug 2766 - Haptic coding bugs and fixes for Linux FF: periodic.…

…phase handled as time instead of angle; + direction clarification

Elias Vanderstuyft

"Horizontal" is not very precise, use "Positive phase" instead.
"Positive" because it's actually waveform(2*pi*t + phase) instead of waveform(2*pi*t - phase).
