automate compile date

[Rick-Methot-NOAA]

per Neal S.
"DATE" is a preprocessor macro that expands to current date (at compile time) in the form mmm dd yyyy (e.g. "Jan 14 2012"), as a string. The DATE macro can be used to provide information about the particular moment a binary was built.

I think the syntax
!!version_info+="#V3.30.17.01Beta;";
!!version_info+=DATE;
!!version_info+=";_safe;Stock_Synthesis_by_Richard_Methot(NOAA)_using_ADMB_12.3";

Great! It sounds like this will be added directly into SS rather than through the github actions, then? That does make some sense....

[Rick-Methot-NOAA]

works great.
added opt vs not_opt
replaced all spaces with underscore
added github site

New output looks like:
#V3.30.18.Beta;_not_opt;_compile_date:_Aug 27 2021;Stock_Synthesis_by_Richard_Methot(NOAA)_using_ADMB_12.3
#Stock_Synthesis(SS)_is_a_work_of_the_U.S._Government_and_is_not_subject_to_copyright_protection_in_the_United_States.
#_Foreign_copyrights_may_apply._See_copyright.txt_for_more_information.
