Taking exports out of .bashrc to avoid redundancy (to keep script clean for future revisions)
After discussion with lowspecman about best places for exports, agree that they should only be [in current script instance] and [in launch script] (instead of [in current script instance] and [in .bashrc], which wouldn't load exports in 100% of cases such as if user logged out of PRoot and tried to log back in on first AnBox install).
Removed some spaces and replaced with tab for formatting uniformity (just since the second stage installer's heredoc sections need to use tabs instead of spaces)
