Delays, negative and otherwise

[alexcjohnson]

Changes to how we handle delays in loops and parameters, per QCoDeS/Qcodes_loop#13 :

• delay=0 is the default in Loops, and does not emit any "negative delay" warnings
• delay and step are separated and renamed in StandardParameter:
  • sweep_step -> step
  • sweep_delay -> delay
  • max_sweep_delay -> max_delay
  • the old names still work (and in fact I haven't updated the tests or existing drivers with the new names yet, but I will do that before this is merged) but will be removed as soon as people have had a chance to merge this into their WIP branches.
  • your parameter can have a delay even if it doesn't have a step - which is the main reason for the name changes, really.

The conflicts make it a tiny bit hard to test,
but it seems to work fine with my simulation branch upon merging anyway.
I did not look at the code, though.
It would be a dancer if not for your own comment:

Actually it looks like there's very little use yet of stepped setters and delays, including exactly none in any of the WIP branches people have published... I've taken out the deprecation code, ONLY the new names are allowed now. Good to go?
