Remove runlines method

[fperez]

The runlines method in interactiveshell is slated for removal. Only a few tests use it, and those cases can probably be replaced with the more robust run_cell(). We should do this before 0.11 is out so people don't continue relying on this deprecated api.

@takluyver, want to take a stab at this one? Given your recent ast work, you're pretty familiar with this part of the code now...

BTW, same goes for push_line. And I see run_source has a lot of duplicate code with run_cell. That can probably be sorted out in the same shot.

[takluyver]

I'll look into it.

[fperez]

great, thanks. I see now this has both low and critical priority... I don't recall which one I tagged it as first, but it should probably only have one :) I'll let you determine which you think is best (or ignore it if you're ready to close).

[takluyver]

I'll put it as medium, just to be contrary. I don't think it's really a blocker for 0.11, although it would be good to tidy up. I'll try to look at it later.
