[Feature request] Add command-line option to specify exact path to config file.

A command-line option something like --config-file /path/to/a/specific/terminalrc

would provide a neat way to easily run multiple instances of xfce4-terminal with separate settings.

My coveted use case, e.g., would be specific palette, background image, font etc. as a type of color coding to better keep track of which window is logged on where.
