42 hours	new neural network arch (faster + better) & minor changes + fixes	tslil clingman
	Gone is the convolutional neural network, for it turns out not only is it more difficult to train, but all of the extra information about board layers didn't make much of a difference at this size. So cnn1986 has been replaced by nn1986, a standard, two-layer, dense nn configured as a binary classifier and (mis)used in that capacity. Note: total number of parameters is unchanged. HARK: this new nn exposes a bug somewhere in ctak. Run ctlm with self-play to see the completely borked board state at the end.

	That i can tell at a glance, the largest relevant change this introduces is flush-to-zero for floats. Some testing is required to ensure that the CNN isn't too sensitive to this. Preferable to that option is to simply train it without relying on subnormal floats in the first place.
42 hours	Welcome geminict!	tslil clingman
	This is a special interface to negamax_cnn1986 which is designed to generate output for use in a CGI tak interface to be used over gemini. Also in this commit is a reformating of the various source files to use the traditional tab width of 8 spaces.

42 hours	TEI interface working!	tslil clingman

42 hours	Fairly important bug fixes to lcdlib, LCD now echoes input!	tslil clingman
	Input polling without line-buffering is done using ncurses, so the buildroot configuration had to change accordingly to include that library. The Makefile changed to accommodate stand-alone building of ct1986 and to include -lcurses where appropriate. There were also some typos about copying ct1986 and ctaklm to the correct directories.
42 hours	Try to squeeze out a little more performance	tslil clingman
	``Common wisdom'' dictates that placements are often better than stack moves, so we bias the generated move list in this fashion. Seems to be a little faster.
