Fixed addpool to specify a profile or algorithm and sets defaults if
nothing specified. Also added a new API function to change multipool
strategy.
Conflicts (resolved):
sgminer.c
Config writer now supports profiles and pool specific values. In
addition, the config writer now makes use of the jansson library to
create proper json objects and save them to the config file. This is
much better than trying to write our own json code.
Conflicts (resolved):
sgminer.c
Updated the config parser to provide better readability and flexibility
in config files. The latest features introduced a really messy way to
handle config files and this update alleviates this by adding the
ability to create profiles and associate them to pools.
Todo: Update the config file writer, in-program options and continue to
break off the config parsing/command line option code out of sgminer.c
to reduce clutter.
