[Move core logic into adblockpluscore repository] Change adblockplus dependency to adblockpluscore in libadblockplus

[kzar]

Background

Once we have successfully moved the core logic from adblockplus to adblockpluscore #2594 we need to replace the adblockplus dependency with adblockpluscore in the libadblockplus repository.

What to change

Replace the adblockplus dependency with adblockpluscore in the libadblockplus repository and ensure the required core code is still included.

Use adblockpluscore at the newer revision hg:82c88024773b, (currently corresponding revision is adblockpluscore:hg:4a2dceec386a==adblockplus:hg:813682c7161e, see #3337).
