Changelog for testing/BuildCraft 7.99.16-pre3

This changelog is relative to the last released version, not the last prerelease!

• Item pipes now send the item all the way into a block, rather than stopping when then item is half-way in.

Ported content:

• The stripes pipe can now extend and retract pipes.

Bug fixes:

• [#4031] Tanks that disallow connections via the new canConnectTo(tank) method doesn't render properly.
