Merge branch 'release'

Extended fix to handle "gp" command also.

Fixed display bug when sourcing a soar file in which a soar command is issued immediately after a production is loaded in that same file. Previously, Soar would not print a linefeed after the production's '*' or '#'. Tokenizer will know compare the current command parsed with the last one. If the last one was an "sp" and the current one is not, it will insert an echo command in between the two. (tokenizer did not have easy access to CLI output, so I had to do it that way.) Previous fix in last big check-in remains. That one added a linefeed, but only after the whole file was sourced.

Prevent linking to python2x_d.lib in windows debug build

Fixed typo.

Disabled macro for debug printing

Properly adding doxygen files.
