Implementation issues with TOI solver

[mtsamis]

There are some bugs in the reworked TOI implementation that make it not work correctly.

• It looks like bullet bodies work, at least to some extend, as can be found out by playing around with the "Add pair" testbed scene.
• Dynamic vs static isn't working. This can be seen in the "Platformer" testbed scene when compared to Box2d.

I need to fix these issues and investigate the correctness of the TOI implementation in general.

I found the Continuous test does not worked as original box2d too. It looks like the CCD algorithm not worked correctly. Here is the screenshot of two testbed:
