replace tput with a safe_tput function (#129)

* replaces tput with a safe_tput function
allows tput to be used on systems that support it but does not error if tput is not available

* add a git push after the sage theme is built and installed
we're unnecessarily waiting because we never actually pushed anything

* remove ||
