Lap time comparison: how fast LMP is vs. F1/GP2/DP01/IRL

[deggis]

Some credits to JAG, who originally did this here but I added more circuits, double-checked and updated most of the times to latest possible year.

Some notes:
-All times are pole laps if not marked with Q2 or FL (fastest lap).
-GP2 '08 car has lots of improvements over 2007 version but "on most circuits it will immediately be around a second faster" (source).
-No idea about possible wet conditions. Probably not as there doesn't seem to be any big abnormalities.
-On American tracks fastest LMP1 and LMP2 listed, on European fastest 908 and R10 listed.
