Another good round of updates and my thanks too.
My favorite part this time around is couriersud's work. :-)

- PORT_ADJUSTER now accepts PORT_MINMAX as well. [Couriersud]
- Implemented a generic implementation to model discrete net lists.
[Couriersud]
* Based on timeslot modelling, the implementation models gate delays
in logic chips.
* Design ready to be split into a generic and a MAME implementation
part.
* Design prepared to merge in discrete components from discrete.*
* Supports code based as well as external net list parsing.
Ultimately, net lists and discrete emulation should share one code
base. The class design was set up to accomplish this. There is no
point in having multiple 555, 7474 implementations around. Most of the
code will be moved to lib/netlist going forward to allow usage in
other projects.
- Pong now uses netlist.h. This implementation reproduces all gate
timing and 555 related effects as described by Dr. H. Holden in his
2012 publication "ATARI PONG E CIRCUIT ANALYSIS & LAWN TENNIS".
