issue2551029: Jinja2 template install error. Issue where template's config.ini not getting updated. Change do_install in admin.py to load config_ini.ini from template before writing tracker's config.ini. This generates an updated config file for the user on install preserving values required tomake tracker work. Added config_ini.ini files to jinja2 and responsive templates to set required values (template_engine and static_files; static_files resp.). Documented new file in doc/tracker_templates.txt and added tests for new admin.py code.

# 3rd party libraries for some of the trackers

The files in theis directory are the sources for files that are used
by the trackers and optional functionality. It includes unminified
javascript and source files used to generate javscript and css.
