Commented out some ununsed code in the hinge limit.
Added a new config option to compile with double precision in bullet. However, that did not solve my oscillation problem with the muscles and low mass.
Commented out some unused code in hinge. Changed the bullet and its unit test to have a single and double compile versions.

Got the double config added back correctly. I removed this config option from everything except the bullet projects because they were not valid for them.
Fixed a bug where the motor locking was not locking at the correct position. It was always defaulting to zero.
I got StdUtils and Bullet animat sim to build with 64 bits.
I believe I have the basics for the 32/64 bit compiles working. I have a beginning on being able to specify this in the GUI. Still need to work on that before actually pushing it out though. I can run the simulation in x64 mode though.
I have the library version setting code in the GUI and project migratations working now. I can convert from double to single.
I also added the ability to set the mass and distance units on a new project.
Added configuration dialogs for exporting standalone simulation files. It lets you choose the params you want. (Physics engine, precision, and binary mode type)
Got all the solution and project files configured to use the premake scripts with single/double and x32/x64 configs for the simulation. The GUI stuff still does not use premakes yet.
