changed the @tpm_plugins to @plugin at the top of scripts/helpers/plugin_functions.sh (a comment just above it says to use @plugin but @tpm_plugins was still being used for some reason)
added tmux in front of the show-option command in tpm_plugins_list_helper(). Otherwise i was getting an error 'show-option command not found'
fix for #246
