"set -g @plugin" syntax doesn't work with nonstandard .tmux.conf location

[skeate]

I like to keep my dotfiles in $XDG_CONFIG_HOME, to keep ~ a little cleaner. Accordingly, tmux is aliased to tmux -f $XDG_CONFIG_HOME/tmux/tmux.conf.

Looking through the source, the set -g @plugin syntax seems to work by parsing the tmux conf file manually? And it looks specifically at /etc/tmux.conf and ~/.tmux.conf. Thus whenever I try to install plugins, it shows no plugins to install.

@tpm_plugins syntax still works, so I'll go back to that, but this should probably be accounted for if @plugin is to be the only way going forward. (perhaps a $TMUX_CONF env var? parsing which tmux?)

whoops, this is a dupe of #57
