Further Progress on BitMaker

It is still happening, just slowly.

My wife is almost done with her studies, and I am at a point now where she no longer has any essays that I need to edit, so hopefully I will get back on track soon.

Just after my last update I decided to look into the possibilities of a library for doing 64 bit operations on 32 bit machines, and soon enough ended up fully implementing a 64 bit mode.

Considering that I was originally planning to leave this feature until (much) later on, I am happy that it is in now and to finish it off I just need to add a flag to the profiles to use 64 bit mode.

Otherwise I still have a little more to do on the recent profiles stuff, and then it will be time for a 2.0 preview release.
