Add new comment to Manual audio clip recording latency compensation

in session properties would be the most suitable IMNSHO :)

also, now that we are at it, the following options should be provided:

• None : disable latency calculation/compensation (not applicable to track/plugin's);
• Auto : latency calculations are done as currently done (default);
• Add : an additional number of frames is added to the default Auto computation (same value to all buses);
• Fixed : a fixed absolute number of frames is set to all audio buses (this being the OP).

cheers
