Adding a segmented run option (like llanfair) and per-segment option.

[YPetremann]

Firstly I play some games with loading times (hl2 for example) and for this I would be glad to see a way of adding pause after a segmentlike with llanfair.

Another thing is that on some game, you do a lot on a single map but you have multiple objectives, so I would like to ask for the possibility to add a per-segment option to pause the timer upon segment completion (which would be used for part preceding loading).
