Install (non-interactive mode) is interactive with xfce4-terminal

[stablestud]

Unfortunately when installing a theme for the xfce4-terminal in non-interactive way, the script still asks if the theme should be applied now.

All done - apply new theme? [y/N] 

I was trying to set the XFCE4_APPLY_CURR_THEME flag to Y but it still is asking me, waiting for user input.

Can we instead set a global flag like APPLY_CURR_THEME which would apply automatically the theme based on its value, if supported by the terminal.

Also can we reduce the output of the script to only show errors, when in interactive mode - possibly also via another flag SILENT_INSTALL?

Thank you
